Various studies suggest that humoral substances, capable of stimulating CFU-S proliferation, are released into the plasma in response to depletion of the CFU-S population by cytotoxic substances such as cyclophosphamide. To test this hypothesis, we placed 0.25 ml of a murine marrow cell suspension with an equal volume of plasma from either normal mice or from mice previously injected with 5 mg of cyclophosphamide into cellulose dialysis tubing. These tubes were then incubated in the peritoneal cavity of mice for 1–7 days. The CFU-S content of the tubes was then assayed. The CFu-S content of suspensions in normal mouse plasma declined to one-fourth of the initial value after 7 days, whereas those in plasma from mice that received cyclophosphamide 7 days previously were essentially unchanged in number. These data suggest that 7 days after injection of cyclophosphamide, the plasma contains a factor that either prevents death of CFU-S or stimulates them to proliferate. An alternative explanation is that normal plasma contains an inhibitor of CFU-S growth that is lacking in plasma of cyclophosphamide-treated mice.

Abstract W/Wv mice with congenitally defective CFU proliferation and their normal, congenic littermates were used as hosts for diffusion chamber (DC) implants. CFU growth in implanted allogenic CF1, or congenic +/+ marrow was significantly greater in W/Wv than in control hosts. When W/Wv mice were “cured” of their hemopoietic defect, CFU proliferation in the DCs decreased, but not to the control level. These observations have provided evidence for humoral control of CFU growth related to a genetic stem cell defect. Diffusion chamber myelopoiesis was also enhanced in W/Wv hosts. In comparison with their congenic controls, W/Wv mice were neutropenic and had decreased numbers of marrow myeloid elements. Thus, a humorally mediated feedback related to a defective myelopoiesis in the hosts might have accounted for increased DC myelopoiesis. However, a “spillover”effect from increased stem cell growth has not been excluded.

Capsule Clinical outcomes using INVOcell device with ICSI. Objective Intravaginal culture of oocytes (INVO) procedure is an intravaginal culture system that utilizes the INVOcell device in which the fertilization and embryo culture occur. In this procedure, the vaginal cavity serves as an incubator for oocyte fertilization and early embryonic development. The objective of this study was to evaluate the clinical outcomes of this intravaginal culture system in intracytoplasmic sperm injection (ICSI). METHODS: A total of 24 cycles INVO-ICSI (study group) and 74 cycles of ICSI (control group) were included in the study. The cleaved oocytes at day 3/ total injected oocytes, embryo quality, pregnancy rate (PR), implantation rate (IR), and miscarriage rate (MR) were compared between both groups. Results At day 3, there was no difference in the cleaved oocyte rate (78.7 and 76.1%) and embryo quality (77 and 86.8%) for the study and control groups, respectively. In the study group, more embryos were significantly transferred compared to the control group (2.63 ± 0.58 versus 1.93 ± 0.25; P < 0.05). PRs, IRs, and MRs were similar for the study group compared with the control group (PR: 54.2% versus 58.1%; IR: 31.7% versus 33.6%; MR: 7.7% versus 20.9%). Conclusions Good PR and IR can be obtained using the INVOcell device, and the INVO-ICSI procedure can be considered as an alternative option to infertile patients.
