MSCs can be obtained and expanded easily compared to ESC without any problems of morality , law and ethic , immunology.

最早在130年前，德国病理学家Cohnheim在研究创口愈合时就推测在创口愈合过程中出现的部分细胞可能来自骨髓。20世纪70年代，Friendenstein发现一小部分骨髓中贴壁最牢固的细胞经数此传代后形成独特的纺锤形外观，具有形成成骨细胞或软骨细胞的能力。80年代以来，许多研究小组进一步证实了Friendenstein分离到的这些细胞是多能的，在体外特定诱导条件下，可以分化为成骨细胞、软骨细胞、脂肪细胞、成肌细胞、神经元等，被称为骨髓间充质干细胞(Bone MarrowMesenchymal Stem Cells，MSCs)。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.
