[Problem] There is no gene transduction method with high efficiency and high specificity for skin, subcutaneous tissue, skin ulcer surfaces, and their constituent cells. More generally, achieving high gene transduction efficiency in vivo is challenging. Additionally, it is difficult to morphologically and functionally regenerate skin appendages and to regenerate lost peripheral tissues of the upper and lower limbs (upper arm, forearm, hand, fingers, thigh, lower leg, foot, toes).[Solution] This invention provides solutions to these challenges through a novel AAV (adeno-associated virus) capsid with high gene transduction efficiency and high specificity for skin, subcutaneous tissue, and skin ulcer surface cells, as well as a novel AAV capsid with high gene transduction efficiency and high specificity for epidermal tissue and its constituent keratinocytes. Additionally, the invention provides a novel tissue-specific promoter with high gene expression efficiency and high specificity for epidermal tissue and its constituent keratinocytes, and a pharmaceutical composition that enhances gene transduction efficiency by co-administering steroids alongside in vivo gene transduction. The invention further includes a pharmaceutical composition that promotes the regeneration, neogenesis, and functional enhancement of skin appendages through in vivo gene transduction, thereby compensating for functional impairments of skin appendages. Additionally, it provides a research and development platform for developing methods to regenerate peripheral and missing tissues of the upper and lower limbs, as well as a pharmaceutical composition for achieving tissue regeneration. Thus, the present invention provides methods for overcoming these challenges.
