真皮乳头是一群位于毛囊基部的间充质细胞,在头发生长的调节中起着重要的作用。因此,这些细胞的体外模型被广泛用于研究毛囊诱导、生长和维持的分子机制。虽然来自啮齿动物毛囊的真皮乳头可以在细胞分离之前被消化,但在人类真皮乳头中发现的独特的细胞外基质组成使得胰蛋白酶和胶原酶等酶不足以将真皮乳头消化成单细胞悬浊液。因此,为了在体外培养人类真皮乳头细胞,必须首先通过微解剖方法从毛囊中分离出乳头。在这篇文章中,我们描述了显微解剖和培养方法,这是我们在实验室中使用的,用于研究人类真皮乳头细胞。
The dermal papilla is a cluster of mesenchymal cells located at the base of the hair follicle which have a number of important roles in the regulation of hair growth. As a consequence, in vitro models of these cells are widely used to study the molecular mechanisms which underlie hair follicle induction, growth and maintenance. While dermal papilla from rodent hair follicles can be digested prior to cell isolation, the unique extracellular matrix composition found in human dermal papilla renders enzymes such as trypsin and collagenase insufficient for digestion of the dermal papilla into a single cell suspension. As such, to grow human dermal papilla cells in vitro, the papilla has to first be isolated via a micro‐dissection approach from the follicle. In this article we describe the micro‐dissection and culture methods, which we use within our laboratory, for the study of human dermal papilla cells.
