Mesenchymal Stem Cells (Mscs)

Stem cells are defined as undifferentiated somatic cells having the ability to produce varieties of fully-differentiated progenies in response to the appropriate environment being provided in vitro or in vivo (1). nowadays, at least four criteria are considered for cells to be known as stem cells .a) such cells must possess ability to undergo extensive proliferation for a long time. this property is called as their self-renewal potential. b) such cells should have a capacity to undergo multilineage differentiation in the presence of appropriate culture condition, for example neural stem cells are able to produce neuron as well as astrocyte and oligodendrocyte
