Tissue Engineering of Urinary Bladder and Urethra: Advances from Bench to Patients
Tissue engineering is defined as the combination of biomaterials and bioengineering principles together with cell transplantation or directed growth of host cells to develop a biological replacement tissue or organ that can be a substitute for normal tissue both in structure and function. Despite early promising preclinical studies, clinical translation of tissue engineering in pediatric urology into humans has been unsuccessful both for cell-seeded and acellular scaffolds. This can be ascribed to various factors, including the use of only non-diseased models that inaccurately describe the structural and functional modifications of diseased tissue. The paper addresses potential future strategies to overcome the limitations experienced in clinical applications so far. The development of smart scaffolds that release trophic factors in a set and timely manner will probably improve regeneration. Modulation of innate immune response as a major contributor to tissue regeneration outcome is also addressed. It is unlikely that only one of these strategies alone will lead to clinically applicable tissue engineering strategies in pediatric urology.
Electrospinning: Application and Prospects for Urologic Tissue Engineering
Functional disorders and injuries of urinary bladder, urethra, and ureter may necessitate the application of urologic reconstructive surgeries to recover normal urine passage, prevent progressive damages of these organs and upstream structures, and improve the quality of life of patients. Reconstructive surgeries are generally very invasive procedures that utilize autologous tissues. In addition to imperfect functional outcomes, these procedures are associated with significant complications owing to long-term contact of urine with unspecific tissues, donor site morbidity, and lack of sufficient tissue for vast reconstructions. Thanks to the extensive advancements in tissue engineering strategies, reconstruction of the diseased urologic organs through tissue engineering have provided promising vistas during the last two decades. Several biomaterials and fabrication methods have been utilized for reconstruction of the urinary tract in animal models and human subjects; however, limited success has been reported, which inspires the application of new methods and biomaterials.
Tissue engineering in urology
Urinary tract is subjected to many varieties of pathologies since birth including congenital anomalies, trauma, inflammatory lesions, and malignancy. These diseases necessitate the replacement of involved organs and tissues. Shortage of organ donation, problems of immunosuppression, and complications associated with the use of nonnative tissues have urged clinicians and scientists to investigate new therapies, namely, tissue engineering.

Бросила взгляд на монитор, потом посмотрела на Грега Хейла.
Премного благодарен, приятель! - крикнул тот ему вслед. - Увидишь Меган, передавай от меня привет! - Но Беккер уже исчез. Двуцветный вздохнул и поплелся к танцующим. Он был слишком пьян, чтобы заметить идущего следом за ним человека в очках в тонкой металлической оправе. Выбравшись наружу, Беккер оглядел стоянку в поисках такси.
- Открылся третий уровень защиты! - Люди в комнате засуетились. На экране агент с короткой стрижкой безнадежно развел руками. - Сэр, ключа здесь. Мы обыскали обоих.
Когда он шел к выходу по главному коридору, путь ему преградил охранник с телефонной трубкой в руке.
