Dear Editor: The histoculture of intact skin on sponge-gel matrices offers many opportunities for tissue engineering and the in vitro study of important processes intrinsic to skin such as hair growth and toxicity to various agents (Li et al., 1991, 1992a, 1992b, 1992c). We have recently exploited this system to demonstrate that liposomes can selectively target hair follicles to deliver small and large molecules including DNA.Liposomes have been widely and successfully used as delivery systems to transport macromolecular substances that can not nor-mally cross the plasma membrane into the cell (Gregoriadis 1984, 1988). We have recently reported that calcein-dye entrapped liposomes specifically targeted hair follicles in histocultured intact skin (Li et al., 1992d). Our results were strongly confirmed by studies by Lieb et al.(1992) demonstrating that liposomal formulations were more efficient than any other vehicle tested for delivery of carboxyfluorescein through the follicular route into the pilose-baceous units with the hamster ear model. We then developed liposome-mediated targeted delivery of melanin into hair follicles and the hair shaft itself in histocultured white-haired mouse skin (Li et al., 1993a). Recently, Yarosh also reported that liposomes allow T4 endonuclease V to penetrate into living skin (Yarosh et al., 1992). These studies have many ramifications including targeted hair growth modifications.
