    Current trends in stem cell therapy for improvement of bone quality
    (F. Hernández y Juan F. Madrid. Universidad de Murcia: Departamento de Biología Celular e Histología, 2014) Yamada, Yoichi; Nakamura, Sayaka; Klein, Ophir D.
    As the average lifespan of humans continues to increase, improvement in the quality of life for elderly people is important. Among the most severe problems during aging are bone loss-associated diseases such as poor fracture healing and osteoporosis. Therapy-induced bone loss such as bisphosphonate-associated osteonecrosis of the jaw also increases in incidence with age. Most of the current treatment strategies are focused on antiresorptive and bone formation pharmacological agents, but it is hard to obtain appropriate bone augmentation and there are concerns regarding their long-term safety without side effects. Therefore, a novel method for improvement of bone quality is required, and stem cells are of great interest as potential therapeutic tools for diseases that remain without clinically effective therapies. In this review, we describe the concept of stem cell-based therapy and evaluate the current progress of cell therapy for the improvement of bone quality. In addition, we report and discuss a new clinical strategy in which improved bone quality was obtained by applying bone-marrow derived MSCs with platelet rich plasma in clinical therapy.

    Treatment and new progress of neonatal hypoxic-ischemic brain damage
    (Universidad de Murcia, Departamento de Biologia Celular e Histiologia, 2020) Yang, Lijun; Zhao, Hehua; Cui, Hong
    Neonatal hypoxic ischemia (HI) results in different extents of brain damage, and immature brain tissue is particularly sensitive to the stimulation of HI. Hypoxic-ischemic brain damage (HIBD) is a common and serious nervous system disease in neonates, for both full-term infants and preterm infants, and is one of the main causes of neonatal death. The surviving infants are often associated with cerebral palsy, mental retardation, and other sequelae, which severely affect quality of life. For term infants, hypoxia and ischemia mainly affect gray matter, whereas in preterm infants, the white matter. However, up to now, inadequate standards and specific measures that can be used to treat hypoxic-ischemic brain injury are available. Recently, in addition to supportive therapy and symptomatic treatment, research on the treatment of hypoxic-ischemic brain injury has focused on the following aspects: hypothermia therapy, stem cell therapy, neuroprotective agents, ibuprofen, and combination therapy. In this review, we will summarize the treatment of HIBD and make suggestions for the future treatment direction
