Abstract
La alopecia androgénica (AGA) es uno de los trastornos de pérdida capilar más prevalentes que afecta a millones de hombres y mujeres en todo el mundo. Los tratamientos actuales se basan en fármacos de acción hormonal, vasodilatadores tópicos o procedimientos físicos como el trasplante capilar. Teniendo en cuenta que estas terapias presentan efectos adversos o tienen un carácter reversible, los tratamientos basados en terapia celular son alternativas emergentes que pretenden estimular los mecanismos regenerativos y restaurar el nicho celular del folículo piloso, alterado en la AGA. Debido a la ausencia de estudios que hayan empleado en exclusividad ASCs aisladas y expandidas en el tratamiento de la AGA en vehículo HTS y/o con un aporte exógeno de ATP, se ha realizado el diseño experimental teniendo en cuenta como tratamientos, ASCs a dosis alta solas y ASCs a dosis baja, media y alta cada una de ellas en combinación con una formulación de ATP diferente. A su vez también ha sido testada la posible eficacia de estas dos formulaciones: ATP liposomado en un 30% de la composición (ATP liposomado) y ATP no liposomado en forma de sal (ATP no liposomado)...
Androgenetic alopecia (AGA) is one of the most prevalent hair loss disorders which affects millions of men and women around the world. Current treatments are based on hormone action drugs, topical vasodilators and physical procedures such as hair trasplant. Due to these therapies are not successful in the long term or have relevant side effects, treatments based oncell therapy are emerging alternatives which aims to enhance altered regenerative mechanisms and promote a cell niche restoration in AGA hair follicles. Due to the absence of an isolated and expanded ASCs in a HTS solution and/or with an exogenous supply of ATP in the treatment of AGA, an experimental design was proposed taking into account a high dose of ASCs alone and a high, medium and low dose of ASCs in combination of a different formulation of ATP. Both formulations consist of: liposomated ATP (30% of the composition is in the form of liposomes) and non liposomated ATP in the form of salt...
