The quantity and survival time of astrocytes, which were differentiated from adult adipose-derived stromal cells after exposure to an inducer containing 3-isobutyl-1-methylxanthine, have thus far been unsatisfactory. The present study investigated the growth and differentiation characteristics of induced astrocytes by observing their growth curves. After induction for 48 hours with an inducer containing 0.5% ethanol, some adult adult adipose-derived stromal cells displayed typical astrocytic morphology. The cell quantity gradually decreased with prolonged induction time. Nestin, glial fibrillary acidic protein, and S-100 expression reached peak levels at 14 days, but neuron-specific enolase was not expressed. These results suggest that the induced astrocytes reached their peak at 14 days. Further optimization of the culture environment may yield mature astrocytes with normal functions, in greater quantity, and prolonged survival time.

爸爸经常帮我买早餐。每次，他都会端着一个白底红花印的大瓷碗出去，回来时，碗里便装满了热腾腾、香喷喷的米粉或云吞。因为热乎乎的汤很烫手，爸爸便又想了一个办法——用一个原本用来盛水果的竹盘子托着碗，這样就不烫手了。不过这样一来，爸爸走路就得很小心了，以免弄洒汤水。每天端着个竹盘子给我“上菜”的爸爸，有时候看起来，还真像古代饭馆里的店小二。 时间久了，爸爸的举动便被他的同事们知道了。有人不解地问：“老
