  • Efficient gene transfer into hematopoietic stem cells is a great tool for gene therapy of hematopoietic disease. Retrovirus have been extensively used for gene delivery and gene therapy. However, current in vitro gene transfer has some obstacles suck as induction of differentiation loss of self-renewal capacity, and down-regulation of homing efficiency for in vitro hematopoietic stem cells transplantation. To overcome these problems, we developed efficient in vitro retroviral transfer technique by direct intra-bone marrow injection (IBM). We identified effective retrovirus gene transfer in bone marrow hematopoietic cells in vitro. Two weeks after retrovirus transfer via IBM injection, we observed stable EGFP gene expression in bone marrow, lymph node, spleen, and liver cells. In addition, $6.4{\pm}2.7%$ of hematopoietic stem/progenitor cells were expressed EGFP transgene from flow cytometry analysis. Our results demonstrate that in vitro retrovirus gene transfer via IBM injection can provide a viable alternative to current or moo gene transfer approach.

  • Although anejaculation is a relatively uncommon occurrence in the general population, over 12,000 new cases are reported annually. Anejaculation may result from spinal cord injury, retroperitoneal lymph node dissection, diabetes mellitus, transverse myelitis, multiple sclerosis, or psychogenic disorders. At least 30% of men with this problem are or will be married and many will seek help to remedy their infertile state. The evolution of technique and instrumentation over the last 30 years has made electroejaculation an accessible and acceptable form of therapy. Recent successes in inducing ejaculation by means of rectal probe electrostimulation or vibratory stimulation combined with assisted reproductive techniques, such as zygote intrafallopian transfer (ZIFT), gamete intrafallopian transfer (GIFT), and in vitro fertilization (IVF), have provided these men means of producing their own biologic offspring. We have experienced a successful pregnancy with electroejaculation and in vitro fertilization in a infertile patient whose husband had an ejaculatory disturbance due to a spinal cord injury. So we report this case with a brief review of literatures.
