Different kinds of stem cells in the development of SARS-CoV-2 treatments

Figure 2 Stem cells classification. According to their origin, stem cells (SCs) are divided into embryonic and adult cells. Embryonic SCs can be obtained from the zygote, morula, or the blastocyst's inner cell mass and possess high potentiality. Adult SCs can be isolated from neonatal and adult tissues (umbilical cord, placenta, bone marrow, adipose tissue, among others). Likewise, the induced pluripotent SCs are considered another kind of adult SCs once they are derived from adult somatic cells but have been genetically reprogrammed. Concerning their potentiality, SCs are divided into totipotent, pluripotent, multipotent, and oligopotent SCs. Thanks to artificial intelligence, the generation of artificial induced pluripotent SCs was reported. iPSCs: Induced pluripotent stem cells.
