With the aim to detect what kind of cells, in addition to erythroid progenitors, could be involved in the pathogenesis of B19 infection in some connective tissue diseases, primary cultures of human fibroblasts (HF) and endothelial cells (HUVEC) were exposed to a B19 positive serum (350 genome copies/cell). The presence of NS1 and VP1 mRNA, in both HF and(More)
In this study we report a preliminary investigation of the feasibility of non-woven/sponge fabrics of a hyaluronan derived biomaterials (benzyl ester of HA (HYAFF-11 FAB, Abano Terme, Italy) for the in vitro culture of rat hepatocytes and rat beta cells. Cell growth on hyaluronan derived biomaterials were tested in the presence of complete medium and in the(More)
Experiences coming from many cell-culture studies has brought about the concept that tissue and organ reconstruction should be performed in a three-dimensional environment as it normally occurs in vivo. As far as endothelial cell culture is concerned, it has been shown that angiogenesis can be successfully achieved only when cells are cultured in the(More)
The difficulty of obtaining significant long-term patency and good wall mechanical strength in vivo has been a significant obstacle in achieving small-diameter vascular prostheses. The aim of the present study was to develop a prosthetic graft that could perform as a small-diameter vascular conduit. Tubular structures of hyaluronan (HYAFF-11 tubules, 2 mm(More)
Successful in vitro reconstruction of skin requires the inclusion of several cell types that give rise in coculture to the specific elements present in native skin, and the appropriate scaffolding structure to house and support these cells. In addition to the two main structural components, epidermis and dermis, one critical apparatus of the skin is a(More)
OBJECTIVE To evaluate a new Hyaluronan-based graft. MATERIAL AND METHODS Hyaluronan-based grafts (HYAFF 11trade mark tube, diameter 2 mm, length 1.5 cm) were implanted in an end-to-end fashion in the abdominal aorta of 15 rats. Histology, immunohistochemistry and electron microscopy were used to evaluate the results at 7, 21, and 90 days. RESULTS At day(More)
INTRODUCTION A greater supply of tendinous tissue can be obtained through tissue engineering technology with increasing application of adult stem cells. It is well known that adipose-derived stem cells (ADSCs), found in abundance in adipose tissue, have the same differentiating capacity as mesenchymal stem cells yet have the advantage of being easily(More)
Tissue engineering is a multidisciplinary field that involves the application of the principles and methods of engineering and life sciences towards i) the fundamental understanding of structure-function relationships in normal and pathological mammalian tissues and ii) the development of biological substitutes that restore, maintain or improve tissue(More)
This paper presents a dermal replacement technique for cutaneous wounds of diverse origin. An autologous tissue-engineered dermal-like structure was implanted in one patient with an acute surgical excision of a nevus and in another patient with a chronic post-traumatic ulcer. The dermal constructs were well integrated with the wound area, and, at 3 weeks,(More)
