Although we have previously reported that several of the HOX homeobox genes are expressed during murine skin development, there is no information about developmental expression of HOX genes in human skin. We have now used reverse transcriptase polymerase chain reaction, in conjunction with a set of degenerate oligonucleotide primers, to identify a subset of HOX genes that are expressed during human fetal skin development. In situ hybridization analyses demonstrated that there were temporal and spatial shifts in expression of these genes. Strong [[HOXA4]] expression was detected in the basal cell layers of 10 wk fetal epidermis and throughout the epidermis and dermis of 17 wk skin, whereas weak signal was present in the granular layer of newborn and adult skin. The expression patterns of [[HOXA5]] and [[HOXA7]] were similar, but their expression was weaker. In situ hybridization analysis also revealed strong [[HOXC4]] and weaker [[HOXB7]] expression throughout fetal development, whereas [[HOXB4]] was expressed at barely detectable levels. Differential HOX gene expression was also observed in developing hair follicles, and sebaceous and sweat glands. None of the HOX genes examined were detected in the adult dermis.<br /> |mesh-terms=* Adult<br /> * Aging<br /> * Embryonic and Fetal Development<br /> * Fetus<br /> * Gene Expression<br /> * Genes, Homeobox<br /> * Gestational Age<br /> * Hair Follicle<br /> * Humans<br /> * Infant, Newborn<br /> * Polymerase Chain Reaction<br /> * Sebaceous Glands<br /> * Skin<br /> * Sweat Glands<br /> * Time Factors<br /> * Transcription, Genetic<br /> <br /> |full-text-url=https://sci-hub.do/10.1046/j.1523-1747.1998.00092.x<br /> }}</div>
