Stem cells and biomaterials transplantation hold a promising treatment for functional recovery in spinal cord injury (SCI) animal models. However, the functional recovery of complete SCI patients was still a huge challenge in clinic. Additionally, there is no clinical standard procedure available to diagnose precisely an acute patient as complete SCI. Here, two acute SCI patients, with injury at thoracic 11 (T11) and cervical 4 (C4) level respectively, were judged as complete injury by a stricter method combined with American Spinal Injury Association (ASIA) Impairment Scale, magnetic resonance imaging (MRI) and nerve electrophysiology. Collagen scaffolds, named NeuroRegen scaffolds, with human umbilical cord mesenchymal stem cells (MSCs) were transplanted into the injury site. During 1 year follow up, no obvious adverse symptoms related to the functional scaffolds implantation were found after treatment. The recovery of the sensory and motor functions was observed in the two patients. The sensory level expanded below the injury level, and the patients regained the sense function in bowel and bladder. The thoracic SCI patient could walk voluntary with the hip under the help of brace. The cervical SCI patient could raise his lower legs against the gravity in the wheelchair and shake his toes under control. The injury status of the two patients was improved from ASIA A complete injury to ASIA C incomplete injury.
Furthermore, the improvement of sensory and motor functions was accompanied with the recovery of the interrupted neural conduction. These results showed that the supraspinal control of movements below the injury was regained by functional scaffolds implantation in the two patients who were judged as the complete injury with combined criteria, it suggested that functional scaffolds transplantation could serve as an effective treatment for acute complete SCI patients.
Stem cells can be defined as units of biological organization that are responsible for the development and the regeneration of organ and tissue systems. They are able to renew their populations and to differentiate into multiple cell lineages.Continue reading
Multiple sclerosis (MS) is a progressively debilitating neurological condition in which the immune system abnormally erodes the myelin sheath insulating the nerves. Mesenchymal stem cells (MSC) have been used in the last decade to safely treat certain immune and infammatory conditions.Continue reading
As the most important barrier for the human body, the skin often suffers from acute and chronic injuries, especially refractory wounds, which seriously affect the quality of life of patients. For these refractory wounds that cannot be cured by various surgical methods, stem cell transplantation becomes an effective research direction. As one of the
adult stem cells, adipose-derived stem cells play an indispensable role in the repair of skin wounds more than other stem cells because of their advantages such as immune compatibility and freedom from ethical constraints. Here, we actively explore the role of adipose-derived stem cells in the repair of cutaneous wound and conclude that it can significantly promote cutaneous wound healing and regeneration. Based on a large number of animal and clinical trials, we believe that adipose-derived stem cells will have a greater breakthrough in the field of skin wound repair in the future, especially in chronic refractory wounds.

Premature ovarian failure (POF) is a common endocrine disease causing female infertility. It is characterized by high gonadotropin expression [follicle-stimulating hormone (FSH) ≥ 40 mIU/mL], low estradiol (E2) expression, and follicular dysplasia in women aged less than 40 years .Continue reading
