Researchers found that McSCs transform between their most primitive stem cell state and the next stage of their maturation depending on their location.

研究人员发现，根据其位置，MscSC细胞会在最原始的干细胞状态和成熟的下一阶段之间进行转变。

These growth factors cause the mesangial cells to regress back to their more immature stem cell state known as mesangioblasts and secrete extracellular structural matrix.

这些生长因子使得系膜细胞退化成为未成熟的干细胞状态（成系膜细胞），并分泌细胞外基质框架。
