Processing of Umbilical Cord Blood | What happens in lab

Once the umbilical cord blood get collected immediately after the delivery , it then reached the lab where the processing of the blood gets starts for extracting out the desired stem cells which are of use.

Since the blood is very crucial and if not processed in time may turns into clot and is of no use afterwards, due to which the it is very essential to proceed with the processing of blood as soon as possible. 

Generally blood consist of many different types of cells namely Red Blood Cells (RBC's), White Blood Cell(WBC's), Platelets, Hematopoetic Stem Cells (HSC's) and plasma and the main motive behind cord blood processing is the extraction of Hematopoetic Stem Cells (HSC's) only and discarding the remains.

Process of Umbilical Cord Blood processing

Initially the sample get inspected and reviewed.Then technicians will proceed with processing.

Please find below the flow chart and explanation for each method  of cord blood processing :

Manual methods of Umbilical Cord Blood Processing

1.Density Gradient solution - This process involves separation of different layers of blood components based  on the principle of gravity using the centrifuge. Once the blood gets separated in to the layer,one layer will be buffy coat which is of use as it contains stem cells and rest will be discarded.It is necessary to make sure that there will not be the presence of even a single red blood cells because having so will restrict the sample usage to the donor only and will produce toxic effects or rejection if used by a different recipient.

Fig 2 : How Density gradient will lead to separation of buffy coat.

2.Hydroxyethyl Starch Solution -It is a process of recovering stem cells by red blood cells depletion.This further involve manual separation of white blood cells by sedimentation with chemical hetastarch to ensure that cord blood units which are being extracted are on an average 99 % pure.

Automated methods of Umbilical cord Blood Proessing

1. AXP - It stands for AutoXpress Platform, which is functionally a closed and fully automatic system for the processing of cord blood and extracting the stem cells.It is an integral component of CBR's proprietary Cell Advantage system. CBR has the highest published average stem cells recovery rate of 99% which is considered best in the the industry.

*AXP and AutoXpress are registered trademarks of Cesca Therapeutics.

2. Prepacyte CB - This process involves red blood cell depletion upto 99% and leads to highest recovery of Colony forming units (CFU),which in a general sense are the stem cells which are used for the treatment of the patient.Discarding all the red blood cells from the blood is very essential which will results in less toxic effects post the treatment.

3. SEPAX  and SEPAX 2 - Both are the fully automated closed system system for the efficient and consistent processing of umbilical cord blood. Both the devices belongs to Biosafe SA .However SEPAX 2 is highly advanced as compared to SEPAX.

Check the difference between sepax and sepax 2.

There are many companies which deals with the cord blood processing and different technique is being used by each of them for the processing and recovery of stem cells however choosing the right technique and using it in a right way is all what is important for getting the stem cells which will be useful for the mankind.

Procedure of umbilical cord blood banking

Cord blood is collected right once birth. the gathering method is painless and safe for you and your baby. In fact, it is so fast and painless that oldsters – held in holding and bonding with their new baby – are usually unaware it's even happened.

Here's however it's done:

1.Clamping and cutting the cord

After you've got delivered your baby, whether or not vaginally or by cesarian, the wire is clamped then cut within the usual manner – either by your partner or your medical supplier.

You can delay cord clamping, as long because the delay is transient – no quite a moment or two. (If cord clamping is delayed too long, the blood within the cord can clot. And once the blood clots, it's of no profit to anyone – it does not attend your baby and cannot be collected for storage.)

2. Extracting the cord blood

Your medical supplier then inserts a needle into the vena on the a part of the cord that is still hooked up to the placenta. The needle does not go anyplace close to your baby.

The blood drains into a group bag. Typically, one to five ounces square measure collected. the whole method takes but ten minutes.

3. Off to the bank!
The blood is shipped to a cord bank, wherever it's tested, processed, and cryopreserved (preserved by controlled freezing) for long-run storage if deemed acceptable per quality standards.

Some family cord blood banks currently supply to gather a section of the umbilical cord additionally to the cord blood. Umbilical cord tissue contains stem cells that square measure completely different from cord blood stem cells, and researchers square measure finding out their doable use.

4.Transplantation

Cryogenic blood-forming stem cells will be thawed and employed in either autologous procedures (when somebody receives his or her own fetal membrane blood in an exceedingly transplant) or allogeneic procedures (when someone receives fetal membrane blood given from some other person — a relative, shut relative, or anonymous donor).

In most cases, these transplants are done solely with youngsters or young adults. that is as a result of the quantity of a cord-blood donation typically is not enough for Associate in Nursing adult's transplant. The larger someone is, the additional blood-forming stem cells he or she desires for a productive transplant.

Umbilical Cord Blood Banking

When you are expecting, you have got many choices to form. thus if you have detected regarding banking umbilical cord blood, you may be curious what it involves — and whether or not it's right for you and your family.

About Cord-Blood Banking

Cord-blood banking essentially means that aggregation and storing the blood from at intervals the funiculus (the a part of the placenta that delivers nutrients to a fetus) when a baby is born.

Cord blood contains blood-forming stem cells, that square measure doubtless helpful for treating diseases that need somatic cell transplants, like sure forms of leucaemia or malignant neoplastic disease, anemia, severe red blood cell illness, and severe combined immunological disorder.

There square measure 2 sorts of banks that store twine blood:

Public banks collect given twine blood for analysis or to be used by anyone WHO might have it. there's sometimes no charge related to this service. when birth, blood is collected, anonymously marked, and sent to a public bank to doubtless save the lifetime of another kid someday.

If you decide on this feature and your kid or a friend later develops a illness that needs a somatic cell transplant for treatment, you will not be ready to get the donation you created to the bank.
Private banks store twine blood for private use by the family. there's a fee related to this service. those who have a case history of illness that may be treated with somatic cell transplants generally take into account this feature.

Less normally, individuals value more highly to in private bank their newborn's twine blood on the off likelihood that sometime their kid or a sick friend may well be treated with it. This observe is not suggested, however, since the prices related to it square measure high and also the possibilities of a friend ever improvisation the twine blood square measure slim.

Like community or hospital blood banks, cord-blood banks square measure regulated by the U.S. Food and Drug Administration (FDA), that has developed standards regulation future cord-blood assortment and storage.

Use of stem cells | Cord Blood VS. Bone marrow transplants

Cord blood transplants and bone marrow transplants is accustomed treat several of constant diseases. however what area unit the variations and is one better?

Although ,cord blood has some major benefits over bone marrow. For one, bone marrow transplants work best with a 6 out of 6 HLA (Human Leukocyte Antigen) match, however, cord blood works well with a 3-5 out of 6 HLA (Human Leukocyte Antigen) match.

Also, as a result of the cord blood cells are "immature" than adult bone marrow cells and are able to develop into any other kind of cell due to which, there's less probability that they're going to attack the host body. that is most likely why cord blood is used for transplants though it isn't an ideal match.

Another advantage is that when cord blood is given to a public bank anyone in United Nations agency is sick will use it right away! And it is frozen up to 10 years and still work.

With bone marrow transplants, doctors got to search through databases to seek out folks that have volunteered to give their marrow. Obtaining bone marrow from donors is terribly painful and leads to future health issues as bone marrow cells are extracted by drilling the bone marrow and must be used contemporary.

So what is the draw back of cord blood? Well, one drawback is that the quantity of blood from one cord and placenta is extremely little. that is not such an enormous drawback once victimization cord blood on youngsters , however, adults are larger and wish additional blood cells.

Scientists are figuring out alternative ways to urge around these issues. One is transplantation two batches of cord blood. Another is attempting to use special tricks to extend the amount of cells in one batch of cord blood.

It's been twenty years since the primary cord blood transplant. Over 6,000 are recorded and for several diseases it's even as sensible and typically even higher than bone marrow transplants. As scientists learn additional concerning cord blood stem cells we'll doubtless get even higher at set diseases.

Cord Blood stem cells | Current uses and future challenges

This is in continuation to list of treatable diseases using stem cells. Moving further, I want you to know what exactly the umbilical cord blood is and how it is being collected.Apart from this I am going to discuss in detail about the future aspects of cord blood stem cells.

Umbilical cord blood was once disposed of as waste material however is presently known for the immature stem cells. Further it has been utilized to treat people with certain blood disorders since 1989.

About Umbilical cord blood 

Once a child is conceived, it is attached to his mother with a cord which consequitively attached with placenta present inside mother's womb and on completion of gestation period cord blood is left in the umbilical cord and placenta. It is moderately simple to gather, with no danger to the mother or child. It contains Haematopoietic Stem Cells (HSC's) and Mesenchymal Stem Cells(MSC's) which are being used for the treatment of all the blood related and organ related disorders respectively.

Cord blood medicines today 

Cord blood is utilized to treat individuals who are suffering from deadly blood related disorders,for example, leukemia, or hereditary blood infections like Fanconi paleness. The cord blood is transplanted into the patient, where the HSCs can make new cells, and help in the recovery of the patient post therapy.

Apart from the blood, cord can also be used for the extraction of Mesenchymal Stem Cells. These cells are helpful for the treatment of organ related disorders like arthritis,  blindness, Type-2 Diebities etc.

Momentum exploration: blood ailments 

A noteworthy confinement of Cord blood transplantation is that the blood acquired from umbilical cord contains lesser number of haematopoeitic stem cells as compared to bone marrow due to which at times treating grown up patients become a challenge for therapists with limited number of cells available. A transplant containing excessively few HSCs may fall flat or could prompt moderate development of fresh recruits in the body. This genuine muddling has been part of the way overcome by transplanting blood from two umbilical lines into grown-ups.  

Much research is centered around attempting to build the quantity of HSCs that can be acquired from one cord blood test by developing and duplicating the cells in the lab. This is known as "ex vivo extension". A few preparatory clinical trials utilizing this method are in progress. The outcomes so far are blended: a few outcomes propose that ex vivo development diminishes the time taken for fresh recruits cells to show up in the body after transplantation; notwithstanding, grown-up patients still seem to need blood from two different umbilical lines . More research is expected to comprehend whether there is a genuine advantage for patients, and this methodology has yet to be affirmed for routine clinical utilization. 

What's to come in future ?

Specialists accept that umbilical cord blood is an imperative wellspring though maximum capacity for treatment of blood issue is yet to be uncovered. Different types of immature cells, for example, affected pluripotent cells may turn out to be more qualified for treating non-blood-related sicknesses, however this inquiry must be replied by further research.

List of Treatable Diseases using Stem Cells

This post is in continuation with using stem cells to treat diseases.Here in this article we are providing you the list of various kinds of diseases which can be treated using stem cells or on which clinical trials are going on .The success in these trials will prove as a gift for the group of people who are suffering from various deadly diseases.

Cord blood stem cell transplants have already changed and saved thousands of lives around the world.They have already been used to treat more than 75 diseases, including numerous maligencies, anemia's, inherited metabolic disorders and deficiencies of the immune system.

Below is the table of diseases for the treatment of which stem cells has been used:

Fig : Blood Related disorders for the treatment of which Cord blood cells has been used.

Apart from the above, there are many other disorders and syndromes which are being treated using stem cells, the list is as follows :

• Myelodysplastic Syndromes (Eg. Acute Myelogenous Leukemia, Thrombocythemia etc.)
• Inherited Metabolic Disorders (Eg. Mucopolysaccharidoses, Gaucher's Disease etc.)
• Histiocytic Disorders (Eg. Histiocytosis-X, Hemophagocytosis etc.)
• Inherited Immune System Disorders (Eg. Leukocyte Adhesion Deficiency, Kostmann Syndrome)
• Inherited Platelet Abnormalities (Eg. Congenital Thrombocytopenia/Amegakaryocytosis)
• Plasma cells disorders (Eg. Multiple Myeloma, Plasma cell leukemia etc)
• Other Maligencies (Eg. Breast Cancer, Wing Sarcoma, Neuroblastoma, Renal Cell Carcinoma)

So far I have discussed about the treatable disease, apart from which there are many other diseases on which clinical trial is going on, using umbilical cord blood.

If the trials will be successful than cord blood banking will rise extensively and proves to be a boon in the field of medical science.

Using Stem Cells to treat Diseases

Cord blood stem cells has been extensively  used for therapies as compared to any other sources of stem cells due to its ready availability and nascent  nature which provides better results post transplant therapy.Apart from this it require the lesser matching (HLA matching) for a therapy using cord blood stem cells as compared to other sources of haemopoetic stem cells it minimises the risk associated with the transplant and making it the best option available for the therapist to use.

Around 25 years ago, the first human transplant using umbilical cord blood stem cells was performed.At the time, treatment of only one disease was possible by using cord blood stem cells.Today, cord blood stem cells can be used in the treatment of nearly 80 diseases and the list continues to develop.

Cord blood stem cells have proven track records on treatment of diseases like Thalassemia, Leukemia, Anaemia, Cerebral Palsy, Diabetes and various blood disorders, bone marrow syndromes, cancers, hemoglobinopathies, Immunodeficiencies, metabolic disorders.

Further more than 300 diseases and conditions are in research progressing towards positive results.
