Francisco Jiménez – författare

Al abandonar su hogar en Bonetti Ranch, una comunidad de trabajadores migrantes compuesta de dilapidadas barracas del ejército, sin agua potable ni instalaciones internas de plomería, Francisco Jiménez parte rumbo a la universidad. Deja atrás a una familia que lucha por pagar la comida y el alquiler, y a un padre abatido y desmoralizado. Lleva con él los recuerdos de muchos años viviendo bajo la pobreza y el prejuicio, y así se adentra en un mundo distinto al suyo.

Y no obstante, mientras mecanografía las tareas de otros estudiantes a cambio de ropa, mientras estudia con empeño y se encuentra con inesperadas ayudas, emplea esos mismos recuerdos de su lucha y su sufrimiento para abrirse paso hacia adelante. Una vez más, las honestas palabras de Francisco Jiménez abrirán los corazones y las mentes de los lectores.

With few true accounts of the Latino experience in America, Francisco Jimenez’s work comes alive with telling details about the warmth and resiliency of family and the quest for identity against seemingly impossible odds.

"Many [students] have commented that your books give them hope and courage and, thanks to you, many are seriously thinking about college for the first time in their lives" --John Padula, teacher, Boston Public Schools

This book aims to comprehensively review the current cell-based strategies under investigation to achieve the regeneration of human hair follicles. The unique capacity of the human hair follicle to self-renew explains why this complex “mini-organ” has always attracted so much interest as a model for researchers to study stem cell biology and regenerative medicine. The hair follicle is considered a main reservoir of cutaneous stem cells, containing several pools of epithelial, melanocyte, and mesenchymal stem cells involved in hair follicle self-regeneration and pigmentation. In addition, while some of the different follicular cell types contribute to hair shaft growth, others participate in very important interfollicular functions such as dermal remodeling, re-epithelialization after wounding, and cutaneous stem cell homeostasis.

 The idea of human hair follicle regeneration either “de novo” or by activating dormant miniaturized follicles is not new, yet still continuesto arouse enormous interest in the pursuit of a definitive cure for baldness. In contrast to hair follicle regeneration in mice, the attempts made with human follicles have been disappointing in terms of efficiency. However, recent advances in stem cell biology—as well as the appearance of new technologies like 3D printing—have revived expectations in this field of research.

 This book is divided into four sections. The first part includes an overview of the strategies used in hair follicle regeneration and a historical summary of the most important achievements to date. Parts two and three comprise the main body of the book, with detailed descriptions of the cells and tissue structures involved in hair follicle regeneration, followed by an elaboration of the different therapeutic strategies, engineering techniques, and a clinician’s perspective of stem cell-based therapies in hair loss treatments. Finally, the fourth part reviews the important contribution of the hair follicle in healing cutaneous wounds through the regeneration and remodeling of the dermis and epidermis after injury, as well as wound induced hair follicle neogenesis that occurs when the skin is injured.
