Angiogenesis is the physiological process where new blood vessels grow from existing ones, in order to replenish tissues suffering from inadequate blood supply. Perhaps the most studied angiogenic process occurs in solid tumors whose growing mass and expanding cells create a constant demand for additional supply of oxygen and nutrients for survival. However, other physiological and clinical conditions, such as wound healing, ischemic events, autoimmune and age-related diseases also involve angiogenesis. Angiogenesis is a well-structured process that begins when oxygen and nutrients are depleted, leading to the release of chemokines and growth factors that attract immune cells, particularly m...
Clearance of apoptotic cells is essential for proper development, homeostasis and termination of immune responses in multicellular organisms. Thus, cellular and molecular players taking part in the sequential events of this process are of great interest. Research in the last 20 years has indicated that specific ligands and receptors take part in the attraction of immune cells toward apoptotic targets and in the interactions between apoptotic cells and professional as well as non-professional phagocytes that engulf them. Moreover, phagocytosis of apoptotic cells (efferocytosis) leads to significant phenotypic changes in the engulfing cells suggesting that it is a major fate-determining event ...

Glioblastoma multiforme (GBM) is a uniformly fatal primary brain tumour. Whilst many therapeutic interventions have been studied pre-clinically very few new therapies have been approved for the use of GBM therapy. These tumours present a unique challenge due to their location within the brain, making delivery of therapeutic interventions challenging. Active immunotherapy represents an attractive avenue for therapy, with activated immune cells being shown to cross the blood brain barrier and penetrate brain tumours. Despite several advances being made in numerous other cancer types, many immunotherapeutic interventions in GBM have failed to make it past phase 3 clinical trials and as of now (2022) no immunotherapeutic interventions have been approved for the therapy of GBM.
Human pluripotent stem cells, including human embryonic stem cells and induced pluripotent stem cells, are a key focus of current biomedical research. The emergence of state of the art culturing techniques is promoting the realization of the full potential of pluripotent stem cells in basic and translational research and in cell-based therapies. This comprehensive and authoritative atlas summarizes more than a decade of experience accumulated by a leading research team in this field. Hands-on step-by-step guidance for the derivation and culturing of human pluripotent stem cells in defined conditions (animal product-free, serum-free, feeder-free) and in non-adhesion suspension culture are provided, as well as methods for examining pluripotency (embryoid body and teratoma formation) and karyotype stability. The Atlas of Human Pluripotent Stem Cells - Derivation and Culturing will serve as a reference and guide to established researchers and those wishing to enter the promising field of pluripotent stem cells.
