OBJECTIVE Numerous methods for isolation of human chondrocytes are reported in the literature, most based on isolation from animal cartilage. Normal human articular cartilage (NHAC) poses particular problems for isolating chondrocytes when compared to animal or other types of human cartilage: a hardy matrix, combined with few and friable chondrocytes makes(More)
The construction of tissue-engineered devices for medical applications is now possible in vitro using cell culture and bioreactors. Although methods of incorporating them back into the host are available, current constructs depend purely on diffusion which limits their potential. The absence of a vascular network capable of distributing oxygen and other(More)
The treatment of cartilage pathology and trauma face the challenges of poor regenerative potential and inferior repair. Nevertheless, recent advances in tissue engineering indicate that adult stem cells could provide a source of chondrocytes for tissue engineering that the isolation of mature chondrocytes has failed to achieve. Various adjuncts to their(More)
Short bowel syndrome (SBS) has always posed a great threat to patients and has been one of the biggest challenges for doctors due to its high morbidity and mortality. So far, parenteral nutrition (PN) and small bowel transplantation remain the only viable therapeutic options. However, sepsis and liver failure associated with PN and limited availability of(More)
It has been recognized that seeding vascular bypass grafts with endothelial cells is the ideal method of improving their long-term patency rates. The aim of this study was to assess the in vitro cytocompatibility of a novel silica nanocomposite, polyhedral oligomeric silsesquioxane-poly(carbonate-urea)urethane (POSS-PCU) and hence elicit its feasibility at(More)
Colorectal cancer is the third most common cause of cancer-related deaths in the Western world. 5-Fluorouracil (5-FU) based chemotherapeutic regimes have been the mainstay of systemic treatment for disseminated colorectal cancer for many years. However, it only produces a 25% response rate due to the drug-resistance. The mitogen-activated protein kinase(More)
Despite advances in surgery and adjuvant regimes, gastrointestinal malignancy remains a major cause of neoplastic mortality. Immunotherapy is an emerging and now successful treatment modality for numerous cancers that relies on the manipulation of the immune system and its effector functions to eradicate tumour cells. The discovery that the pan-epithelial(More)
For over 30 years, stem cells have been used in the replenishment of blood and immune systems damaged by the cancer cells or during treatment of cancer by chemotherapy or radiotherapy. Apart from their use in the immuno-reconstitution, the stem cells have been reported to contribute in the tissue regeneration and as delivery vehicles in the cancer(More)
OBJECTIVE The formation of an endothelial cell layer on the luminal surface of cardiovascular devices, especially bypass grafts, is an important attribute in order to improve their patency. Endothelial progenitor cells (EPCs) have a potential role in the endothelialisation of bypass grafts. We hypothesised that a novel approach to improve endothelialisation(More)
Colorectal cancer (CRC) is characterized by the partial suppression of apoptosis, which in turn gives tumours a selective advantage for survival and can cause current chemotherapy approaches to be ineffective. Recent progress in understanding the mechanisms of apoptosis in colorectal carcinogenesis has provided potential new targets for therapy. Here, we(More)
