What Are Stem Cells?

Stem cells are a group of identical cells which develop and grow into different types of cells. According to Medical News Today, in most common situations, stem cells form from embryo's and adult tissue, which are also known for their potential to develop into different cells.

Embryonic Stem Cells

"Embryonic stem cells are derived from a four- or five-day-old human embryo that is in the blastocyst phase of development."(source). Before the embryonic stem is produced, the fertilized egg, a zygote, starts to multiply it's cells. Once the group of cells is set in the uterus, it becomes a blastocyst. The blastocyst consists of an inner and outer mass. The outer mass, the

This all depends on the health of our body and how capable our stem cells are. In the video above, the man who's stem cells failed to maintain his health, turned to transplant therapy to remain his physical health. However, even with the perks of avoiding such diseases or lowering the effects, there are many ethical issues. According to StemCellres.com, other potential stem cells have been discovered, as well as the pursuing of the idea to artificially increase their potential within our body, raising ethical issues. Even if these newly discovered stem cell types have the power to control our body's health more than embryonic or adult stem cell, which naturally developed in our body, adds risk to the patient's long term health. In the aspect of embryonic stem cells, an embryo is at the stage of developing into a living being, where if therapy is used to artificially develop these cells, the risks of killing them may raise. Since embryos are becoming living, killing the cells, even if not intentionally, through therapy is considered
