    • Methods and compositions for increasing trichogenicity of cells in culture are provided. One embodiment provides culturing dissociated mammalian dermal cells in vitro in the presence of an effective amount of one or more sonic hedgehog (Shh) pathway agonists to increase the trichogenicity of the dissociated mammalian dermal cells compared to untreated dissociated mammalian dermal cells. The cell culture optionally includes epidermal cells. Preferred Shh agonists include, but are not limited to CUR-0236715 and CUR-0201365 available from Curis, Inc. Trichogenicity is measured using the Aderans Hair Patch Assay™. The cultured dermal cells can be maintained in culture in the presence of the one or more Shh agonists for at least 1 to 7 or more days prior to harvest. The treated, cultured dermal cells can be used to treat hair loss in a mammalian subject, preferably a human, by implanting them in an effective amount to induce hair follicle formation.

    • Biomarkers for identifying trichogenic cells have been identified. The biomarkers include microRNA as wells as mRNA and proteins. Certain biomarkers are upregulated in trichogenic cells compared to non-trichogenic cells; whereas, other biomarkers are down-regulated in trichogenic cells compared to non-trichogenic cells. The cells can be dermal cells, epidermal cells, or a combination thereof. Preferably the cells are mammalian, more preferably the cells are human. One embodiment provides a method for selecting trichogenic cells by assaying the cells for expression of one or more biomarkers for trichogenicity, and selecting the cells having increased expression of the one or more biomarkers relative to a control, wherein increased expression of the a biomarker in the cells is indicative of trichogenicity. Preferably, the one or more biomarkers are selected from the group consisting of hsa-miR-200c, hsa-miR-205, hsa-miR-200a*, hsa-miR-200a, hsa-miR-141, hsa-miR-182, DEPDC1, hFLEG1, ESM1, TOME-1, THBD and combinations thereof.

    • A method assay for rapidly and reproducibly generating hair follicles from dissociated epithelial and mesenchymal cells is disclosed. The method serves both as a tool for measuring the trichogenic (i.e., hair growth-inducing) property of cells and for studying the mechanisms dissociated cells employ to assemble an organ. In a method of this application dissociated cells, isolated from newborn mouse skin, are injected into adult mouse truncal skin, hair follicles develop. This process involves the aggregation of epithelial cells to form clusters which are sculpted by apoptosis to generate “infundibular cysts”. From the “infundibular cysts” hair germs form followed by follicular buds and then pegs which grow asymmetrically to differentiate into cycling mature pilosebaceous structures. Using various techniques, exposure of the “infundibular cysts” by puncturing, piercing, or scratching the skin and, in an approach, covering the exposed cysts with a wound dressing material produced egressing hair follicles.
    • 公开了一种用于从解离的上皮和间充质细胞中快速和可重复地产生毛囊的方法测定法。 该方法既用于测量细胞的致毛体(即毛发生长诱导)性质和用于研究解离的细胞用于组装器官的机制。 在这种方法中,从新生小鼠皮肤分离的解离的细胞被注射到成年小鼠的截肢皮肤中,形成毛囊。 该过程涉及上皮细胞的聚集以形成通过凋亡而雕刻以产生“漏斗状囊肿”的簇。 从“漏斗状囊肿”毛发细胞形式,然后是滤泡芽,然后是不对称生长的分离成循环成熟的皮脂状结构的栓。 使用各种技术,通过穿刺,刺穿或刮伤皮肤暴露“漏斗状囊肿”,并且在使用产生流出毛囊的伤口敷料材料覆盖暴露的囊肿的方法中。
