Mechanism Of Cell Differentiation Pdf Download
In mammals, only the zygote and subsequent blastomeres are totipotent, while in plants many differentiated cells can become totipotent with simple laboratory techniques. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics. 146 (1): 1836. Journal of Cell Biology. PMID16923388. Mammalian cell types.
The ductility of these microenvironments are unique to different tissue types. PMID14623229.

Three transcription factors, OCT4, SOX2, and NANOG the first two of which are used in iPSC reprogramming are highly expressed in undifferentiated embryonic stem cells and are necessary for the maintenance of their pluripotency. It is thought that they achieve this through alterations in chromatin structure, such as histone modification and DNA methylation, to restrict or permit the transcription of target genes. doi:10.1016/j.pbiomolbio.2015.01.006. International Publishing House.

The elasticity of the microenvironment can also affect the differentiation of mesenchymal stem cells (MSCs which originate in bone marrow.) When MSCs are placed on substrates of the same stiffness as brain, muscle and bone ECM, the MSCs take on properties of those respective cell types. Matrix sensing requires the cell to pull against the matrix at focal adhesions, which triggers a cellular mechano-transducer to generate a signal to be informed what force is needed to deform the matrix.
