#自然简报# 【本月最佳科学图片】干细胞生物学家、牙医山田峻太朗表示,在合适条件下,牙齿最内层(牙髓)干细胞可以诱导成具有特定形状和特征的神经细胞(如图)。牙髓细胞源自神经嵴,神经嵴负责形成胚胎的神经系统以及面部和颅骨中的骨骼。研究人员希望牙髓干细胞有一天能够在再生医学中得到应用。

They ran through the forest at a steady pace,hour after hour,the sun rising higher and the day growing warmer.Buck was wildly glad.He knew he was at last answering the call,running by the side of his forest brother toward the place from where the call surely came.Old memories were coming upon him fast, and he was awakening to these memories from his ancestors.He had done thing before,somewhere in another world he hardly remembered,and he was doing it again.Now, he was running free in the open,the loose earth under his feet, and the wide sky over his head.~~~The wolf moved on toward the place from where the call surely came,then returned to him,touching noses and making actions as though to encourage him.But Buck turned about and started slowly walking back.
