Stem Cells & Tissue Regeneration
Stem cells are undifferentiated cells which have the capability of self-renew in which they make copies of themselves and can differentiate in which they develop into more number of specialized cells that can be found in multicellular organisms. There are many different types of stem cells based on that originates from different places in the body or that are formed at different stages in our lifetimes. In mammals, there are 2 broad varieties of stem cells: embryonic stem cells, that are isolated from the inner cell mass of blastocysts, and adult stem cells, that are found in numerous tissues. By exploiting similar molecular and cellular pathways, the embryonic development occurs through tissue regeneration following injury or health diseases generally. Additionally, several embryonic tissues, like the medulla spinalis, heart, and limbs have some regenerative potential and will utilize mechanisms that may be exogenously activated in adult tissues.
