induced pluripotent stem (IPS) cells differ from those currently in place for human embryonic stem (ES) cells. An IPS cell is created artificially from skin‚ fat and fibroblasts by reprogramming patient ’s own cells. Scientists believe IPS cells to be a promising source for treating diseases. An ES cell is created by destroying an embryo. Other scientists think ES cells will also be a promising source because it is composed of your own DNA‚ so the immune system won ’t reject the cell. While scientists

1. Ovum a. Definition: the female reproductive cell that is capable of developing into a new member of the same species after fertilization. It is also called the egg. b. Structure: It is large in size (as large as a sesame seed). It is one of the largest cells in the human body. It is a spherical cell. It is not mobile (static). c. Function: It carries the set of chromosomes contributed by the female. It creates a good environment for the fertilization of the sperm. It also provides nutrients for

California have revealed a molecular mechanism that directs the chance and role of cells during the process of animal development. The researchers’ discovery shows remarkable findings that are promising in the advancement of cancer and stem-cell research. The hypothesis of this article relates to even though each individual cell contains the complete DNA code‚ only small portions of this DNA code are activated. Therefore‚ the cell has a certain function instead of others. Every single gene in the DNA code

life and curing disease. Embryonic stem cells are the solution to the many unanswered questions surrounding these priorities. Many people question why scientists cannot simply use adult stem cells for their research instead of using embryonic stem cells. Adult stem cells have been researched for a much longer period of time and some treatments have successfully been developed from them. There are a couple of major constraints on the use of adult stem cells. They have proven to be very difficult
