Stem Cell Culture Human embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst‚ an early-stage embryo. To culture these stem cells under controlled environments‚ one first must have a growth medium. This growth medium is made with DMEM/F12‚ which is cell culture medium‚ a 20 percent Knockout Serum Replacement‚ 100 μM β-Mercaptoethanol‚ 1 percent non-essential Amino Acid‚ and a Basic Fibroblast Growth Factor. This medium is then changed out everyday

advantages of cellphone. It helps people to overcome the obstacles of space to be able to communicate easily and effectively and enjoy many kinds of entertainment.

This advantage is very useful in emergency situations‚ for example‚ when you get lost or have an accident‚ you can call others for help

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

------------- Nov 09‚ 2010 Cell Phones = Cancer? You may have heard on the news or even from your own mother that holding your cell phone too close to your head or using it too much will cause brain damage.

Stem Cells: Future of Failure? When does a sperm and egg begin to resemble what we call a fetus? Research has shown that at four weeks‚ the embryo is the size of an seasame seed (New Health Advisor). The cells that make up this sesame seed could be the future of regenerative medicine. Stem cells are the cells made during the process of fertilization. They are the first traces of humans‚ making them basically a blank slate for all types of cells. They can become essentially any type of cell in the

types of skin cancer; melanoma‚ squamous cell‚ and basal cell carcinoma. Out of the three skin cancers basal cell carcinoma (BCC) is by far the most common. BCC accounts for 90% of all skin cancers. Basal cell carcinoma is also the easiest to treat for the simple fact it rarely metastasize. Bcc tend to stay in the same general area and cause damage to tissues by growing and invading surrounding tissue. Some people are more susceptible to basal cell carcinoma than other.
