Repeated autologous umbilical cord blood infusions are feasible and had no acute safety issues in young babies with congenital hydrocephalus.

Background: Babies with congenital hydrocephalus often experience developmental disabilities due to brain injury associated with prolonged increased pressure on the developing brain parenchyma. Umbilical cord blood (CB) infusion has favorable effects in animal models of brain hypoxia and stroke and is being investigated in clinical trials of brain injury in both children and adults. We sought to establish the safety and feasibility of repeated intravenous infusions of autologous CB in young babies with congenital hydrocephalus.

The ERBB4 intracellular domain (4ICD) regulates NRG1-induced gene expression in hippocampal neurons.

The NRG1 growth factor and ERBB4 receptor have been identified as leading schizophrenia risk genes. Although NRG1 and ERBB4 have been shown to modulate neuronal functions involved in schizophrenia, including both GABAergic and glutamatergic synapses, the exact molecular mechanisms remain poorly understood. Here we investigated ERBB4 intracellular domain, 4ICD, transactivator function in rat hippocampal cultures by inhibiting γ-secretase mediated ERBB4 regulated intramembrane proteolysis (RIP).

Differences in quality between privately and publicly banked umbilical cord blood units: a pilot study of autologous cord blood infusion in children with acquired neurologic disorders.

Background: A pilot study was conducted to determine the safety and feasibility of intravenous administration of autologous umbilical cord blood (CB) in young children with acquired neurologic disorders. Most CB units (CBUs) were electively stored in private CB banks. Unlike public banks, which utilize specific criteria and thresholds for banking, private banks generally store all collected CBUs.

Umbilical cord stem cell transplantation.

Objectives: To discuss the history, current state, and future directions of umbilical cord blood (UCB) transplantation as it relates to the emerging field of cellular therapies.

Data Sources: Research studies, articles, and personal experiences.

Conclusion: Transplantation using hematopoietic stem cells from UCB is a life-saving option for patients with select oncologic and immunologic diseases, bone marrow failure, hemoglobinopathies, and inborn errors of metabolism.

Unrelated donor umbilical cord blood transplantation for inherited metabolic disorders in 159 pediatric patients from a single center: influence of cellular composition of the graft on transplantation outcomes.

Outcomes of 159 young patients with inherited metabolic disorders (IMDs) undergoing transplantation with partially HLA-mismatched unrelated donor umbilical cord blood were studied to investigate the impact of graft and patient characteristics on engraftment, overall survival (OS), and graft-versus-host disease (GVHD). Patients received myeloablative chemotherapy (busulfan, cyclophosphamide, ATG) and cyclosporine-based GVHD prophylaxis. Infused cell doses were high (7.

Transplantation of umbilical-cord blood in babies with infantile Krabbe's disease.

Background: Infantile Krabbe's disease produces progressive neurologic deterioration and death in early childhood. We hypothesized that transplantation of umbilical-cord blood from unrelated donors before the development of symptoms would favorably alter the natural history of the disease among newborns in whom the disease was diagnosed because of a family history. We compared the outcomes among these newborns with the outcomes among infants who underwent transplantation after the development of symptoms and with the outcomes in an untreated cohort of affected children.

The ERBB4/HER4 receptor tyrosine kinase regulates gene expression by functioning as a STAT5A nuclear chaperone.

In the lactating breast, ERBB4 localizes to the nuclei of secretory epithelium while regulating activities of the signal transducer and activator of transcription (STAT) 5A transcription factor essential for milk-gene expression. We have identified an intrinsic ERBB4 NLS (residues 676-684) within the ERBB4 intracellular domain (4ICD) that is essential for nuclear accumulation of 4ICD. To determine the functional significance of 4ICD nuclear translocation in a physiologically relevant system, we have demonstrated that cotransfection of ERBB4 and STAT5A in a human breast cancer cell line stimulates beta-casein promoter activity.
