direct reprogramming
|
the process of taking fully, mature differentiated stem cells and inducing them to become another cell type without going through the stem cell state

|
embryo
|
the product of a fertilized egg, from the zygote until the fetal stage

in vivo
|
within living, experiment done using a whole, living organism

|
molecular pathway
|
a series of interactions between genes, proteins, and other bio factors that lead to a bio effect like differentiation, cell diving, production of antibodies, cell homing, ....

|
protein marker
|
stem cells display characteristic set of protein molecules on cell surface called markers that can be used to make a preliminary identification
