Currently the clinical standard of care for treatment of extensive peripheral nerve damage is the autograft, which consists of a donor nerve from the patient implanted to bridge the site of injury. This technique, although providing a non-immunogenic solution to guide in nerve regeneration, is limited by several constraints including donor site morbidity. To address these concerns, our lab has ...

Induced pluripotent stem cells (iPSCs) hold great promise for cell therapies and tissue engineering. Neural crest stem cells (NCSCs) are multipotent and represent a valuable system to investigate iPSC differentiation and therapeutic potential. Here we derived NCSCs from human iPSCs and embryonic stem cells (ESCs), and investigated the potential of NCSCs for neural tissue engineering. The differ...

Three-dimensional (3D) printing technology has revolutionized tissue engineering field because of its excellent potential of accurately positioning cell-laden constructs. One of the main challenges in the formation of functional engineered tissues is the lack of an efficient and extensive network of microvessels to support cell viability. By printing vascular cells and appropriate biomaterials,...

The identification of multipotential mesenchymal stem cells (MSCs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. This review article focuses on the biology of MSCs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering...

Tissue engineering and regenerative medicine are interrelated terms and go hand in hand whether we discuss about cells (of any kind especially stem and progenitor cells), bio-materials as matrices (2D films, 3D forms of scaffolds, nanofibers, hydrogels, nanoparticles, aerogel, microcapsules, mats, biogel for 3D printing, blends of naturals and/or synthetics , and others), and addition of bioact...

Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...

Tissue-engineered biomaterials have existed approximately 40 years as simple biomimetic structures. Replacement of human tissue with new tissue can be accomplished by generating replacements outside of the body or in situ in the body. In each case, the key elements are described as the tissue engineering triad of scaffolds, cells, and signals. Scaffolds can be produced synthetically or derived ...
