Goals are: to reconstruct a human urethral substitute containing a mature urothelium and a functional vascular network.
The aim of this study was to design a dermal substitute containing adipose derived stem cells (ADSC) that can be used to improve the regeneration of skin on difficult wound beds by stimulating rapid neovascularization.
The recent development of a bioengineered skin substitute containing human dermal fibroblasts with an epidermal layer of human keratinocytes derived from a stable cell line affords the opportunity to develop genetically modified, indication-specific tissues.
It not only provides the microenvironment similar to the stem cell niche within the human body favorable for ex vivo culture and amplification of ESCs but can be used as the dermal scaffold in constructing a skin substitute containing ESCs for the repair of full-thickness skin defects.
For binding, GST-protein was incubated with 30 µl of glutathione sepharose 4B in a total volume of 200 µl NET-2 buffer (50 mM Tris.HCl, pH 7.5, 150 mM NaCl, 0.5% NP-40 substitute, containing 0.1 mg/ml of MBP-CHC(1 1074) or mutant versions.
Multicellular skin substitutes containing PVA borate networks display a linear cellular organization, reduced cellularity and the formation of a keratinized epidermis that resembles normal skin.
Seeding of the underside of the decellularized dermal skin substitutes containing human neonatal foreskin keratinocytes with human umbilical vein endothelial cells (HUVEC) prior to the transplantation produced a successful outcome (Schechner et al. 2003).
Tissue engineering, a cross between the science of living organism and that of engineering, aims to replace, maintain or improve human tissue functions, by means of tissue substitutes containing living elements.
The aim of the study was to evaluate the use of a decellularised scaffold and its re-endothelialisation in vitro in order to create human vascular substitutes containing venous valves.
In order to have a completely defined protocol for generating hematopoietic progenitors, we tested two serum substitutes, containing human serum albumin, human recombinant insulin and human transferrin (HIT and Serum Replacement 3).
