Ever since the disease was first mentioned in the medical literature in 1981, AIDS has spread into nearly every nation on earth and has caused more extensive terror, fear and anxiety than any other medical catastrophe in the twentieth century. It¿s high point now. More than three million people around the world die of AIDS each year and, so far-off, more than 25 million people have died of the disease. Today, at least 40 million people are infected and there are more than 14,000 new infections every day. New data reveals that HIV/AIDS epidemic in India is smaller than previous estimates. But the overall number of HIV cases is still very high ¿ and is spreading like a wild fire and if not stopped quickly it will be harmful for the existence of human life on earth.

Embryonic Carcinoma Cells (EC) to z¿o¿liwy nowotwór z komórek rozrodczych, który najcz¿¿ciej wyst¿puje w j¿drach. Komórki EC s¿u¿¿ jako model do badania rozwoju embrionalnego u ludzi. Komórki te s¿ pluripotencjalnymi potworniakami, które pochodz¿ z transformowanych komórek zarodkowych. Komórki EC s¿ komórkami macierzystymi takich guzów i s¿ ogólnie uwäane za z¿o¿liwe odpowiedniki komórek ES. Linia komórek NTERA-2 to pluripotencjalne ludzkie komórki potworniakoraka. NTERA-2 ma wiele wspólnych cech z ludzkimi komórkami ES. Ponadto globalna ekspresja tych komórek jest bardzo podobna do niezró¿nicowanej ekspresji hESC. Komórka NTERA-2, podobnie jak ich ludzki odpowiednik po potraktowaniu kwasem retinowym, ró¿nicuje si¿ w mieszan¿ populacj¿ komórek linii neuronalnej. Badanie ma na celu monitorowanie liczebno¿ci transkryptów genów, które wcze¿niej by¿y zaangäowane w ró¿nicowanie neuronów, a mianowicie PAX6, NOGGIN, NEUROD i NESTIN, a tak¿e próbuje rzuci¿ troch¿ ¿wiat¿a na potencjalnego kandydata do ró¿nicowania.

Embryonic Carcinoma cells (EC) are malignant germ cell tumor that occurs most often in the testes.EC cells serves as a model for studying embryonic development in humans.These cells are pluripotent teratocarcinomas that are derived from transformed germ cells.EC cells are stem cells of such tumors and are generally considered to be the malignant counterparts of ES cells.The NTERA-2 cell line is pluripotent human teratocarcinoma cell.NTERA-2 shares many characteristic with human ES cell. Also, the global expression of these cells is highly similar to undifferentiated hESC expression. NTERA-2 cell as like their human counter part on treatment with Retinoic acid gets differentiated into a mixed population of cell of neuronal lineage. The study aims at monitoring the transcript abundance of genes that have previously been implicated in neuronal differentiation, namely PAX6, NOGGIN, NEUROD and NESTIN and also tries to throw some light on potential differentiation specific candidate.
