🩻 Stem cells Created Tags Describe the difference in potency of Totipotent and pluripotent Totipotent stem cells can differentiate into all cell types including extra- embryonic tissues while pluripotent stem cells has the potential to differentiate into almost any cell types except extra embryonic tissue DO NOT WRITE PLACENTA as it is a subset of the extra embryonic tissues Totipotent stem cells can organise into an entire organism but pluripotent stem cells lack self-organising ability to form an entire organism Describe the normal functions of blood stem cells in a living organism Undergo self renewal to maintain its population of cells/ provide continuous supply of blood stem cells Can differentiate into blood cells to replace worn out/damaged cells Blood stem cells include myeloid and lymphoid stem cells Lymphoid stem cells can differentiate into lymphocytes such as B cells and T cells Myeloid stem cells can differentiate into red blood cells, neutrophils,eosinophils,basophil,monocytes,platelets Mistakes Do not provide functions of specialised blood cells Jul y 14 , 2025 1113 AM St em cells 1

Ethical issues of ipc Procedure Of harvesting ES cells destroy the embryo which has the potential to develop into a full-sized organism/ akin to taking a human life Intentional creation of embryos with the intention of using them for research and destroying them in that process is considered active killing and violates respect for nascent human life; Harvesting of oocytes R! embryos is invasive/painful retrieval from the women / / Medical risk of oocyte reducing the number and possibly the quality of remaining oocyte for future reproductive purposes Increasing risk of exploitation of women for commercial benefits; Informed consent of donors of surplus ES cell lines from frozen embryos from IVF may not be obtained / donors may not fully understand the implications of the donation/confidentiality of the donor may not be protected;/Patient may not fully understand the moral issue arising from the use of stem cell for their consent; ES cells from donor may exhibit unknown long term effects that range from incompatibility to tumor formation in recipient and recipient may not fully understand the implications; Technologies used to produce stable stem cell lines can be licensed and patented by the biotechnology companies, only the rich has access to and can afford the stem cell therapies that come with high costs; Creation of ES cells using nonhuman oocytes may give rise to chimeras that appear part human and part animal / have characteristics of both humans and animals; The implantation of human stem cell into animals during experimentation may cause development of human part on animalsʼ; Defining features of stem cells Able to undergo self-renewal by mitotic cell division Unspecialised/not terminally differentiated St em cells 2
