| 1 | Therapeutic potential of human embryonic stem cells in type 2 diabetes mellitus显示文摘AIM:To evaluate the safety and efficacy of human embryonic stem cells(h ESCs)for the management of type 2 diabetes mellitus(T2DM).METHODS:Patients with a previous history of diabetes and its associated complications were enrolled and injected with hE SC lines as per the defined protocol.The patients were assessed using Nutech functional score(NFS),a numeric scoring scale to evaluate the patients for 11 diagnostic parameters.Patients were evaluated at baseline and at the end of treatment period 1(T1).All the parameters were graded on the NFS scale from 1to 5.Highest possible grade(HPG)of 5 was considered as the grade of best improvement.RESULTS:Overall,94.8%of the patients showed improvement by at least one grade of NFS at the end of T1.For all the 11 parameters evaluated,54%of patients achieved HPG after treatment.The four essential parameters(improvement in glycated hemoglobin(HbA 1c)and insulin level,and fall in number of other oral hypoglycemic drugs with and without insulin)are presented in detail.For Hb A1c,72.6%of patients at the end of T1 met the World Health Organization cut off value,i.e.,6.5%of HbA 1c.For insulin level,65.9%of patients at the end of T1 were able to achieve HPG.After treatment,the improvement was seen in 16.3%of patients who required no more than two medications along with insulin.Similarly,21.5%of patients were improved as their dosage regimen for using oral drugs was reduced to 1-2 from 5.CONCLUSION:hE SC therapy is beneficial in patients with diabetes and helps in reducing their dependence on insulin and other medicines. | Geeta Shroff | 2016 | World Journal of Stem Cells2016，8，7： | 2 |
| 2 | Morphogenesis of human embryonic stem cells into mature neurons under in vitro culture conditions显示文摘AIM To describe the morphogenesis of different neuronal cells from the human embryonic stem cell(h ESC) line,SCT-N,under in vitro culture conditions.METHODS The directed neuronal cell line was produced from a single,spare,pre-implantation stage fertilized ovum that was obtained during a natural in vitro fertilization process. The h ESCs were cultured and maintained as per our proprietary in-house technology in a Good Manufacturing Practice,Good Laboratory Practice and Good Tissue Practice compliant laboratory. The cell line was derived and incubated in aerobic conditions. The cells were examined daily under a phase contrast microscope for their growth and differentiation. RESULTS Different neural progenitor cells(NPCs) and differentiating neurons were observed under the culture conditions. Multipotent NPCs differentiated into all three types of nervous system cells,i.e.,neurons,oligodendrocytes and astrocytes. Small projections resembling neurites or dendrites,and protrusion coming out of the cells,were observed. Differentiating cells were observed at day 18 to 20. The differentiating neurons,neuronal bodies,axons,and neuronal tissue were observed on day 21 and day 30 of the culture. On day 25 and day 30,prominent neurons,axons and neuronal tissue were observed under phase contrast microscopy. 4',6-diamidino-2-phenylindole staining also indicated the pattern of differentiating neurons,axonal structure and neuronal tissue. CONCLUSION This study describes the generation of different neuronal cells from an h ESC line derived from biopsy of blastomeres at the two-cell cleavage stage from a discarded embryo. | Geeta Shroff | 2016 | World Journal of Experimental Medicine2016，6，4： | 0 |
| 3 | Nutech functional score: A novel scoring system to assess spinal cord injury patients显示文摘AIM To develop a new scoring system, nutech functional scores(NFS) for assessing the patients with spinal cord injury(SCI).METHODS The conventional scale, American Spinal Injury Association's(ASIA) impairment scale is a measure which precisely describes the severity of the SCI.However, it has various limitations which lead to incomplete assessment of SCI patients.We have developed a 63 point scoring system, i.e., NFS for patients suffering with SCI.A list of symptoms either common or rare that were found to be associated with SCI was recorded for each patient.On the basis of these lists, we have developed NFS.RESULTS These lists served as a base to prepare NFS, a 63 point positional(each symptom is sub-graded and get points based on position) and directional(moves in direction BAD → GOOD) scoring system.For non-progressive diseases, 1, 2, 3, 4, 5 denote worst, bad, moderate, good and best(normal), respectively.NFS for SCI has been divided into different groups based on the affected part of the body being assessed, i.e., motor assessment(shoulders, elbow, wrist, fingers-grasp, fingers-release, hip, knee, ankle and toe), sensory assessment, autonomic assessment, bed sore assessment and general assessment.As probability based studies required a range of(-1, 1) or at least the range of(0, 1) to be useful for real world analysis, the grades were converted to respective numeric values.CONCLUSION NFS can be considered as a unique tool to assess the improvement in patients with SCI as it overcomes the limitations of ASIA impairment scale. | Geeta Shroff Jitendra Kumar Barthakur | 2017 | World Journal of Methodology2017，7，2： | 0 |
