SHH信号通路调控默克尔细胞发育中分子机制的研究

触觉作为胚胎发育时期重要的感觉系统,在生物个体的本体感觉、空间感知、及情感发育等方面都起着重要作用。触觉感受器默克尔细胞(Merkel cell, MC)介导了触觉穹隆中MC-神经突复合体行使的轻触觉感知,其发育机制研究一直是皮肤触觉领域的核心问题。对MC发育的分子机制深入研究,将有助于解决发育、衰老及临床疾病中触觉相关问题。已有研究表明MC发育可能包括Gli1+干细胞、Atoh1+前体细胞以及成熟MC三个阶段,且Shh信号是必需的条件,但具体发育分化过程及相关调控机制还不清楚。本项目拟应用转基因动物模型和体外长时程培养表皮干细胞体系,进一步深入研究Shh信号通路活化的转录因子组合在维持Gli1+干细胞及其往Atoh1+前体细胞特化过程中转变的表观遗传调控机制,为默克尔细胞的发育、再生和与触觉相关疾病的临床研究提供理论依据和实验基础。
