Types Of Stem Cells

There are several types stem cells found having there own characteristics.Out of which the details of few are mentioned below :

Embryonic Stem Cells

The embryonic  are the cells which are found inside the blastocyst stage of embryo and are are being harvested  from the the inner cells mass of blastocyst.

These cells can give rise to any kind of cell present inside the human body.(220 different types of cells are present inside human body )

Process of harvesting and differentiating the embryonic stem cells

There are certain ethical issues involves as it is considered that by harvesting the embronic stem cells which involves the destruction of the embryo ,we are killing a possible human life though these cells are having great therapeutic potential by the help of which one can save the life of dying human.

Adult Stem Cells
Adult stem cells are the cells which are found in all the individuals (Infant,children & adults) and are being harvested from already developed t in specific tissue ,

These cells can give rise to specialised cell present inside specific tissue or organ of the human body such as heart, brain , kidney , liver etc.

These stem cells basically supports :

• Circulatory system
• Nervous system
• Respiratory System
• Digestive system
• Skeletal system
• Muscular System

Nowadays , adult stem cells are the cells which are being used for the treatment of various kinds of diseases and mostly being used in case of bone marrow transplantation .And future possibilities for the treatment of several life threatening diseases is based these cells only.

Induced Pluripotent Stem Cells (IPSC's)
Induced pluripotent stem cells are adult, differentiated cells that hev been experimentally "reprogrammed" into a stem cell like state.

These cells can be made from readily available cells including fat, skin, and fibroblasts (cells that produce connective tissue).

Process of creating IPSC'S

 The "reprogramming" process introduces genetic modifications, the safety of using iPS cells in patients is uncertain.

Importance of Stem Cells

Stem cells are important as they are having great potential in the medical field .Stem cells can regerate and repair the damge tissue and for the same reason were being used from a longer period of time for bone marrow transplantation but now because of medical advancement in this field and various clinical trials these cells are being used for the treatment of various blood related and organ related diseases which comprises of leukemia,lymphoma,cancer,diabetes,hearing loss,vision loss etc.

Introduction to Stem Cells

Stem Cells

Stem Cells are the basis cells of our body or we can say the master cells which plays a very crucial and beneficial role inside the human body.These are the cells which are undifferentiated means capable to differentiate into various specialised cells(220 different types) and have the ability to divide for a longer period of time.The stems cells which are capable to give rise to every kind of cells ,tissues and organs are found inside the embryo and are responsible for the development of foetus body .
