BACKGROUND Mesenchymal stem or stromal cells (MSCs) are a heterogeneous population that can be isolated from many tissues including umbilical cord Wharton's jelly (UC-WJ). Although initially limited in studies such as a hematopoietic stem cell transplantation adjuvant, an increasing number of clinical trials consider MSCs as a potential anti-inflammatory or(More)
The incidence of soft tissue tumours, both malignant and benign, is very common. However, the coexistence of 4 types of histopathology is rare and the aim of this article is to present one treated in our Department. An 87-year-old Greek man was treated in our Department for a huge tumour on his back, under local anaesthesia. The pathology report of the(More)
BACKGROUND Each year, more than 800,000 vascular and cardiac surgeries are performed therefore, there is a great need for suitable material for bioprosthetic operations. Porcine pericardium is a double-walled sac that covers the heart and can be used in vascular and cardiac thoracic surgery. OBJECTIVE The aim of the present study was to evaluate the(More)
Major achievements in creating decellularized whole tissue scaffolds have drawn considerable attention to decellularization as a promising approach for tissue engineering. Developing a tissue-engineered small-diameter (≤2 mm) vascular graft, using decellularized human umbilical arteries (hUAs), for reconstructive surgery is a challenging task. Polymers used(More)
