1174-损伤诱导的CD34+平滑肌祖细胞驱动血管重塑

from 聊聊Sci

这项研究揭示了血管损伤后一种关键的细胞演变机制。研究人员发现,原本处于收缩状态的血管平滑肌细胞(SMC)在受损后会转变为一种高增殖性的CD34+瞬时祖细胞(STPC)。这些STPC不仅是构成病理性内膜增生的主要细胞来源,其增殖能力也远超普通的平滑肌细胞。实验证明,通过遗传学手段清除这些祖细胞,可以显著减轻血管内膜的异常肥厚。此外,研究确定了DCLK1蛋白是驱动平滑肌细胞向祖细胞状态转变的核心分子开关。这一发现为治疗动脉粥样硬化和支架内再狭窄等血管重塑性疾病提供了全新的精准靶点。References:Lu Y, Ni H, Shen J, et al.
