On Tissue Engineering and Regenerative Medicine of Skin and Its Appendages

Metrics details. Engineering of biologic skin substitutes has progressed over time from individual applications of skin cells, or biopolymer scaffolds, to combinations of cells and scaffolds for treatment, healing, and closure of acute and chronic skin wounds. Skin substitutes may be categorized into three groups: acellular scaffolds, temporary substitutes containing allogeneic skin cells, and permanent substitutes containing autologous skin cells. These advances have contributed to reduced morbidity and mortality from both acute and chronic wounds but, to date, have failed to replace all of the structures and functions of the skin. Among the remaining deficiencies in cellular or biologic skin substitutes are hypopigmentation, absence of stable vascular and lymphatic networks, absence of hair follicles, sebaceous and sweat glands, and incomplete innervation.

Skin is the largest organ of the body and is necessary for survival, since it performs many functions such as providing a physical barrier to the external environment, sensation, retention of normal hydration and thermal regulation. Significant skin loss is associated with high mortality and morbidity in the Significant skin loss is associated with high mortality and morbidity in the acute phase, and with physically and cosmetically drastic scarring in the long term. There are a number of tissue-engineered products in the clinic that are used as skin substitutes to promote healing of traumatic burn and diabetic wounds, producing results that satisfy the barrier function of the skin. The current tissue engineered skin although constitutes one of the most advanced tissue constructs, yet it lacks several important functions including those provided by the appendages such as the hair follicles, sebaceous and sweat glands. Dermal skin substitutes have been developed to promote regeneration of the dermis and although the incorporation of growth factors to accelerate healing has also been explored, none of them have addressed the issue of regenerating the hair follicles, sebaceous or sweat glands and their important function. The next generation tissue engineered products should take into consideration the regeneration of its appendages taking cues from developmental biology and stem cell engineering.

Skin Tissue Engineering and Regenerative Medicine: From skin repair to regeneration

Correction of these deficiencies depends on regulation of biologic pathways of embryonic and fetal development to restore the full anatomy and physiology of uninjured skin.

Skin Tissue Engineering and Regenerative Medicine

The skin is the largest human organ system. Loss of skin integrity due to injury or illness results in a substantial physiologic imbalance and ultimately in severe disability or death. From burn victims to surgical scars and plastic surgery, the therapies resulting from skin tissue engineering and regenerative medicine are important to a broad spectrum of patients. This work expands on the primary literature on the state of the art of cell therapies and biomaterials to review the most widely used surgical therapies for the specific clinical scenarios. Biomedical researchers in the fields of tissue engineering and regenerative medicine; stem cell researchers.

Metrics details. Normal wound healing is a dynamic and complex multiple phase process involving coordinated interactions between growth factors, cytokines, chemokines, and various cells. Any failure in these phases may lead wounds to become chronic and have abnormal scar formation. Thus, much effort has been focused on developing novel therapeutic approaches for wound treatment. Stem-cell-based therapeutic strategies have been proposed to treat these wounds.

Стратмор вздохнул: - Двадцать лет назад никто не мог себе представить, что мы научимся взламывать ключи объемом в двенадцать бит. Но технология не стоит на месте. Производители программного обеспечения исходят из того, что рано или поздно появятся компьютеры типа ТРАНСТЕКСТА.

 - Ему ведь всего тридцать лет. - Тридцать два, - уточнил Стратмор.  - У него был врожденный порок сердца.

Не спуская со Стратмора ледяного взгляда, Сьюзан сделала шаг вперед и протянула к нему руку с зажатым в ней предметом. Стратмор был почти уверен, что в руке Сьюзан сжимала беретту, нацеленную ему в живот, но пистолет лежал на полу, стиснутый в пальцах Хейла. Предмет, который она держала, был гораздо меньшего размера.

 Городская больница, - буркнула зачумленная секретарша.

Оказавшись на улице, человек в очках в тонкой металлической оправе достал крошечный прибор, закрепленный на брючном ремне, - квадратную коробочку размером с кредитную карту. Это был опытный образец нового компьютера Монокль, разработанного ВМС США для проверки напряжения аккумуляторов в труднодоступных отделениях подводных лодок - миниатюрный аппарат, совмещенный с сотовым модемом, последнее достижение микротехнологии. Его визуальный монитор - дисплей на жидких кристаллах - был вмонтирован в левую линзу очков. Монокль явился провозвестником новой эры персональных компьютеров: благодаря ему пользователь имел возможность просматривать поступающую информацию и одновременно контактировать с окружающим миром.

На фотографии она была изображена наклонившейся над постелью, в одних трусиках. Как выяснилось, кто-то из криптографов сосканировал фотографию из порножурнала и приставил к телу головы модели голову Сьюзан. Получилось очень даже правдоподобно. К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного. Два часа спустя был издан ставший знаковым приказ: СОТРУДНИК КАРЛ ОСТИН УВОЛЕН ЗА НЕДОСТОЙНЫЙ ПОСТУПОК С этого дня никто больше не доставлял ей неприятностей; всем стало ясно, что Сьюзан Флетчер - любимица коммандера Стратмора.

У шифров-убийц обычно есть функция злопамятства - чтобы не допустить использования метода проб и ошибок.
