Abstract
Asos hujayralari tanamizdagi barcha hujayralarning ajdodi hisoblanadi. Ular hali differentsiatsiyalashmagan hujayaralar hisoblanadi. Bu hujayralarning bo’linishi natijasida hosil bo’lgan yangi hujayralar turli xil organ va to’qimalarga aylanish qobilyatiga ega. Bu xusussiyati tufayli organizmda shikastlangan hujayralarning o’rnini yangi, yosh hujayralar bilan to’ldiradi. Shunday qilib, asos hujayralari o’z-o’zini ko’paytirish va organizm uchun differentsialashgan hujayralar ishlab chiqarish funksiyasini bajaradi. Asos hujayralari bo’linib yangi hujayaralari hosil qilgandan so’ng, ularning oldida ikkita yo’l bo’ladi: 1) yangi hujayra o’zgarmasdan organizmda asos hujaralar zaxirasini to’ldirib turish; 2) differensial hujayraga aylanish. Lekin, asos hujayralari organizmning hamma qismida ham uchrayvermaydi. Ular suyak iligi, qon, yog’ to’qimasi va kindik qonida uchraydi. Bu hujayralardan hozirgi kunda regenerativ tibbiyotda foydalanilmoqda.
