    • 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。

    • The present invention provides nonradioactive NIR optical imaging agents based up on the structure of retinoid acid derivatives. The nonradioactive NIR optical imaging agent has been evaluated at the cellular level by confocal microscopy, and in vivo in a whole animal using a various xenograft models. The specific uptake of this agent in human cancer cells and multiple xenograft models demonstrate that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for early stage cancer studies and diagnoses. Also, the present invention provides that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for visualization of drug redistribution within the body which is useful in determining the optimal biological dose. Ultimately, the visualization data can be used as an analytical tool to reduce any systemic toxicity.
    • 本发明提供了基于类视黄酸衍生物的结构的非放射性近红外光学成像剂。 已经通过共焦显微镜在细胞水平上评估了非放射性近红外光学成像剂,并且在使用各种异种移植模型的整个动物体内进行了体内评估。 该药物在人类癌细胞和多种异种移植物模型中的特异性摄取表明,非放射性近红外染料标记的类视黄醇代谢物和/或类似物可用于早期癌症研究和诊断。 此外,本发明提供了非放射性近红外染料标记的类视黄醇代谢物和/或类似物可用于体内药物再分布的可视化,其可用于确定最佳生物剂量。 最终,可视化数据可用作分析工具,以减少任何全身毒性。
