stem cells therapy.

benda lar stem cell ni.. aku rasa masuk final sub genetics ni,huhu xp  study yuk! 

lala.. slama aku masih bisa bertahan slama aku masih bisa bernafas slama tu aku akan tuntut ilmu. walaupun pemalas tapi aku percaya darjat seseorang itu bukan berdasarkan brapa guni duit dia ada tp ilmu didada itulah ukurannya. ilmu tu walau dimana saja adalah tetap milik orang islam.. pertama skali aku nak mintak maaf sebarang kecatatan ilmu yang aku nak bgtau sbb ni first time aku google and baca pasal stem cell, orite.

oke back to stem cell, there are 3types : 

1. totipotent
2. pluripotent (embryonic stem cell)
3. multipotent.

but only pluripotent and multipotent stem cells are being use for therapy. what is stem cell therapy exactly? based on my understanding, stem cell therapy is a treatment of disease or injury by introducing the stem cell into the lost organ or damaged tissue.

embryonic stem cell (es), have the greatest potential of development. such as for bone marrow transplantation.

oke scientist had discovered how es develop and works ?

1. the egg is fertilized to form an embryo

google image, embryo.

2. 1 to 5 days later, the embryo divides and then it form blastocyst

3. 2 days later the es is visible and able to form tissue

4.  then the cells are removed and grown in a petri dish. the cells creat a line of stem cell when they dividing.

5. the by support of nutrients, drugs and other factors, the stem cells differentiate into specific body cells that are unable to divide such as muscle cell, pracreatic islet cell and nerve cell.

there's other way to harvest stem cell such harvesting peripheral blood stem cell. this can treat blood cancer, leukemia, and liver chirrhosis and also others related.

there are actually soooooo many research on stem cell.

p/s : tak larat da.. mau tidur.. nanti2 lar sambung pulekk.. korang cuba fikir cmna in future, bla scientist guna cell therapy then letak mutagens skit, mesti akan hasilkan mutant, benda ni mungkin  leh jadi baik or buruk, tapi apa yang kita perlu risaukan adalah betrayal of the nature. cam dlm muvie underworld 2 and 3, x-men, and blablabla.. *ni kaki tengok dvd ni..
 kaki tak da mata lar na tngok.. :P
