Hematopoietic stem and progenitor cells and potentials for application in fetal cell replacement therapy
Fetal cell replacement therapy or in utero hematopoietic cell transplantation (IUHCT) is proposed as a non-myeloablative alternative to bone marrow transplantation (BMT) for a number of inborn immunologic, hematologic and metabolic disorders. IUHCT represents the method through which variable …

Neural Stem Cells - interaction with the brain and prospects for cell replacement therapy for Stroke
… as astrocytes and oligodendrocytes. Neural stem cells (NSCs) could potentially be used to develop novel therapies to restore loss of function after stroke. We generated a NSC line derived as monolayer cultures from the human fetal striatum, termed NS, and described the in vitro and in vivo …

CELL REPLACEMENT THERAPY FOR PARKINSON’S DISEASE: The importance of neuronal subtype, cell source and connectivity for functional recovery
… therapeutic options. One such idea is cell replacement therapy (CRT). CRT aims to replace neurons that have degenerated in PD, with donor cells that have the potential to functionally re-integrate into the host circuitry. This involves transplantation of developing midbrain cells from …

Applications for human neural stem cell-derived motor neurons in amyotrophic lateral sclerosis: Cell replacement therapy and disease modeling
… explore the potential of human fetal neural stem cells (hNSCs) to replace lost motor neurons. The therapeutic efficacy of stem cell transplantation would depend greatly on the survival of grafted stem cell-derived motor neurons in the microenvironment of the spinal cord in ALS. Previously, we …

Generation of cells for cell-replacement therapy: Specification of neural precursors in vivo and in neural stem cell cultures
Cell replacement therapy of neurodegenerative disorders aims to substitute the degenerating cells with new functional neurons. Clinical trails with patients suffering from Parkinson’s or Huntington’s disease have generated proof-of-principle results that neural precursors taken from the developing …

Towards cell replacement therapy in Parkinson’s disease. Proteoglycans and Nogo-A as modulators of axonal growth in midbrain dopaminergic neurons
… for PD are highly warranted. The concept of cell replacement therapy in PD is based on the idea that the diminished dopamine levels in the striatum would be restored by the functional DNs, obtained from donated, electively aborted fetuses, and subsequently injected into the patients’ …

Cell replacement strategies in the central nervous system in two mouse models of neuronal damage: potential therapeutic targets and promising drugs
The recent discovery of adult neural stem cells (NSC) has revealed the therapeutic potential of neurogenesis in the development of new regenerative therapies to treat the damaged adult brain. Physiologically, the generation of new neurons from NSC occurs mainly within two regions of the adult …

Human neural stem cells: region-specific properties and prospects for cell therapy
Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural …

A microfabricated 3-D stem cell delivery scaffold for retinal regenerative therapy
… result in the degeneration of the photoreceptor cells and can ultimately lead to blindness in patients. There is currently no cure for AMD or RP, and only a few methods exist for slowing the progression of these diseases. Although there has been much recent headway in cell replacement therapy to …

Identification of dopamine neuron progenitors in the embryonic midbrain and stem cell cultures - Studies on the role of neuronal subtype and differentiation state for cell replacemen in a rodent model of Parkinson's disease
… therapies. A promising alternative approach is cell replacement therapy, which aims to replacethe lost dopamine-producing neurons by transplanting cells with equivalent properties. Clinical transplantations using cells obtained from foetal VM tissue have provided the proof-of-principle that cell …

A model for analysis of the effects of redundancy and error correction on DRAM memory yield and reliability
… free DRAM. Error correction codes (ECCs) and cell replacement are two methods currently used in isolation of each other in order to solve two of the problems with this manufacturing process: increasing reliability and increasing yield, respectively. Possible solutions to this problem are …

Stem cell-based regenerative pharmacology for the treatment of diabetes mellitus
Stem cell-based regenerative pharmacology is aimed at establishing stem and progenitor cells as effective treatment for preventing disease and facilitating organ replacement or repair. Diabetes mellitus (DM) is a group of chronic metabolic disorders characterized by high blood glucose levels. Type …

Investigation of growth factors and cytokines that suppress adult stem cell asymmetric cell kinetics
Adult stem cells are potentially useful in many biomedical applications that can save lives and increase the quality of a patient's life, such as tissue engineering, cell replacement, and gene therapy. However, these applications are limited because of the difficulty in isolating and expanding pure …

Encapsulation as a 3D model for human embryonic stem cell propagation and differentiation
… disease caused by the destruction of the beta cells of the pancreas. Current treatments for are whole pancreas or islet transplantation, which is limited by scarcity of cadaveric pancreata. Therefore, developing a cell replacement therapy with renewable sources of surrogate beta cells is …

Chemogenetics, Induced Neurons and Pluripotent Stem Cells: Towards Advanced Gene and Cell Therapies Targeting Epilepsy
… the feasibility and potential for novel gene and cell therapy approaches, which hold better promise for neurological disorders, while particularly targeting epilepsy. Epilepsy is a multifactorial neurological disorder affecting 1% of the population. Available pharmacological therapies are merely …

Molecular Mechanisms Involved In Krabbe's Disease
La leucodistrofia di Krabbe o a cellule globoidi è un disturbo autosomico recessivo a carico del gene codificante per galactosilcerebrosidase (GALC). GALC è coinvolto nel catabolismo di due lipidi molto prodotti nel processo di formazione della guaina mielinica: galactosilceramide e psicosina. A …

Targeted Epigenetic Editing to Increase Adult Pancreatic Β-Cell Proliferation
β-cell replacement therapy is potentially a curative approach in treating diabetes, as demonstrated by the success of pancreatic islet transplantation in type 1 diabetes. However, there are an insufficient number of organ donors to meet the demand of this disease, which is increasing in prevalence. …

The Maturation of Human Pluripotent Stem Cell-Derived Retinal Ganglion Cells and Their Degeneration in Glaucoma
… leading to the degeneration of retinal ganglion cells (RGCs) and eventual blindness. A need exists to better understand the maturation of human RGCs as well as their degeneration, with the goal of developing new therapeutics diseases like glaucoma. Human pluripotent stem cells (hPSCs) provide an …

Proteomic Characterization of Human Multipotent Stromal Cells Secreted Proteins with Therapeutic Potential for β-cell Regeneration
Novel strategies to stimulate the expansion of β-cell mass in situ are warranted for diabetes therapy. Cell-replacement therapies for the treatment of diabetes have become a focal point in recent years. Endogenous regeneration of β-cell mass has been demonstrated using human multipotent stromal …
