Wharton's Jelly Stem Cells: A Novel Cell Source for Oral Mucosa and Skin Epithelia Regeneration

2013

Abstract Perinatal stem cells such as human umbilical cord Wharton's jelly stem cells (HWJSCs) are excellent candidates for tissue engineering because of their proliferation and differentiation capabilities. However, their differentiation potential into epithelial cells at in vitro and in vivo levels has not yet been reported. In this work we have studied the capability of HWJSCs to differentiate in vitro and in vivo to oral mucosa and skin epithelial cells using a bioactive three-dimensional model that mimics the native epithelial-mesenchymal interaction. To achieve this, primary cell cultures of HWJSCs, oral mucosa, and skin fibroblasts were obtained in order to generate a three-dimension…

Long-Term in vivo Evaluation of Orthotypical and Heterotypical Bioengineered Human Corneas.

2020

Purpose: Human cornea substitutes generated by tissue engineering currently require limbal stem cells for the generation of orthotypical epithelial cell cultures. We recently reported that bioengineered corneas can be fabricated in vitro from a heterotypical source obtained from Wharton’s jelly in the human umbilical cord (HWJSC). Methods: Here, we generated a partial thickness cornea model based on plastic compression nanostructured fibrin-agarose biomaterials with cornea epithelial cells on top, as an orthotypical model (HOC), or with HWJSC, as a heterotypical model (HHC), and determined their potential in vivo usefulness by implantation in an animal model. Results: No major side effects …

Use of decellularized tracheas for airways engineering

2016

Background/Objective: Tracheal stenosis produces serious dyspnea. In some cases, a defective correction or timely intervention can lead to the death of the patient. The Hospital Clinico Universitario de Valencia is a reference hospital for the treatment of patients with airway problems exhibiting complex tracheal stenosis. Surgery is limited to a maximum length of 6-7 cm and it is not exempt of mortality (3-5%). In this study we have study the useful of decellularized porcine tracheas to be used in airway regenerative medicine. Methods: Three porcine tracheas were cut in 3 cm rings and exposed to SDS 2% for up to four weeks. Cell content was evaluated by fluorescence microscopy (DAPI) weekl…
