The purpose of this study is to determine the safety and preliminary effectiveness of human central nervous system stem cells (HuCNS-SC®) transplantation in patients with Connatal Pelizaeus-Merzbacher Disease (PMD). Enrolled subjects will be transplanted with HuCNS-SC cells into the brain and will receive immunosuppression for nine months. The study observation period is for one year after transplant surgery. Thereafter, subjects will be enrolled in a long-term observational follow-up study for four years.
Allocation: Non-Randomized, Control: Uncontrolled, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label

A fellow eye controlled study of HUCNS-SC sub-retinal transplantation in subjects with bilateral GA AMD. All subjects will be assigned to HUCNS-SC transplantation.
Patients with infantile or late infantile NCL have either a reduced amount of, or are missing, the palmitoyl protein thioesterase 1 (PPT1) enzyme or the tripeptidyl peptidase 1 (TPP-I) enz...
The Chongqing intracerebral hemorrhage study is a multi-center, prospective, observational study led by professor Qi Li from Chongqing Medical University. Professor Peng Xie will be the se...
Intracerebral hemorrhage is bleeding into the brain and is a major cause of stroke and other complications. Brain injury from intracerebral hemorrhage occurs in two phases. The early phas...
The aim of this project is development of a comprehensive, prospective, multinational, multicenter, hospital-based, data repository for patients with intracerebral hemorrhage.
Pelizaeus Merzbacher disease (PMD) is a dysmyelinating disorder of the central nervous system caused by impaired differentiation of oligodendrocytes. This study was prompted by findings that anti-musc...
Generation of precisely patterned neural cells from human pluripotent stem cells (hPSCs) is instrumental in developing disease models and stem cell therapies. Here, we provide a detailed 16-d protocol...
Chagas' disease (CD) is caused by infection with the protozoan Trypanosoma cruzi. The disease can affect the heart and/or the gastrointestinal (GI) tract, but around 70% of infected individuals remain...
Identification of lobar spontaneous intracerebral haemorrhage associated with cerebral amyloid angiopathy (CAA) is important because it is associated with a higher risk of recurrent intracerebral haem...
Nonalcoholic fatty liver disease (NAFLD) is a growing cause of chronic liver disease globally and nonalcoholic steatohepatitis is projected to become the most common indication for liver transplantati...
A rare, slowly progressive disorder of myelin formation. Subtypes are referred to as classic, congenital, transitional, and adult forms of this disease. The classic form is X-chromosome linked, has its onset in infancy and is associated with a mutation of the proteolipid protein gene. Clinical manifestations include TREMOR, spasmus nutans, roving eye movements, ATAXIA, spasticity, and NYSTAGMUS, CONGENITAL. Death occurs by the third decade of life. The congenital form has similar characteristics but presents early in infancy and features rapid disease progression. Transitional and adult subtypes have a later onset and less severe symptomatology. Pathologic features include patchy areas of demyelination with preservation of perivascular islands (trigoid appearance). (From Menkes, Textbook of Child Neurology, 5th ed, p190)
Preparative treatment of transplant recipient with various conditioning regimens including radiation, immune sera, chemotherapy, and/or immunosuppressive agents, prior to transplantation. Transplantation conditioning is very common before bone marrow transplantation.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
An organism that, as a result of transplantation of donor tissue or cells, consists of two or more cell lines descended from at least two zygotes. This state may result in the induction of donor-specific TRANSPLANTATION TOLERANCE.
Transplantation between individuals of the same species. Usually refers to genetically disparate individuals in contradistinction to isogeneic transplantation for genetically identical individuals.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
