The transition of fetal haematopoietic sites in mice was examined histologically from 12.5-day embryos (E12.5) until 10 days of age (D10), and the expression of the adhesive molecules VCAM-1 and fibronectin was examined immunohistologically. Erythropoiesis occurred in the liver (E12.5-18.5), spleen (E18.5-D4) and bone marrow (D6-10), in that sequence. Even(More)
We examined the expression of VCAM-1 and MAdCAM-1 after bone marrow transplantation (BMT). We also examined the influence of alpha(4)beta(7) integrin blockade on the homing of cells to the bone marrow and spleen. The expression of VCAM-1 and MAdCAM-1 by endothelial cells in the spleen and bone marrow was examined by immunoelectron microscopy using colloidal(More)
Mouse and vole embryos were allogeneically and xenogeneically transferred into pseudopregnant CD-1 and immunodeficient (scid) female mice, and we investigated the distribution of immunocompetent cells, uterine natural killer (uNK) cells, mast cells and macrophages, in the implantation sites on days 6, 7 and 8 of gestation. The survival rate of the vole(More)
The estrus female Etawah cross bred goats were synchronized estrus by controlled internal drug release (CIDR) implants for 10 days combined with PGF2α injection, and continued by artificial insemination (AI) within the hours of 24 period. Vaginal epithelium was taken to determine estrus cycle of the goats without estrus synchronization. The estrus responds(More)
Reproductive features of newly bred Russian voles (Microtus rossiaemeridionalis) as a laboratory animal were studied. This species is a copulatory ovulator, and most couples copulated 6 to 16 h after pairing. The gestation period varied from 18 to 22 days (mean +/- SD: 20.6 +/- 0.9, n = 72), and the average litter size was 4.6 +/- 1.9 (n = 125). Compared(More)
Eight Etawah cross bred does were divided into two groups based on body condition score (BCS). Group I (BSC 2, body weight 25-30 kg; n = 4), and Group II (BSC 3, body weight, 35-40 kg, n=4). All does received intravaginal controlled internal drug release devices (CIDR) for 10 days, and a prostaglandin F2α at 48 h before CIDR removal. Estrus detection was(More)
The research was conducted to examine the effect of supernatant embryonic media culture injection into mice uterine at 2 days prior to embryo transfer implantation rate, indicated by the presence of implanted embryos and leukemia inhibitory factor (LIF) in the uterine. Swiss Albino mice were divided into two experimental groups, supernatant embryonic media(More)
Development of better bovine’s assisted reproduction device in livestock industry requires a temperature controller to help researcher choosing best bovine’s spermatozoa. This study aims to design bovine’s semen temperature controller prototype which fully controlled using PID (Proportional Integral Derivative) algorithm. Temperature target is achieved(More)

A motorized moving stage with submicron precision is needed to support cellular manipulation e.g. in vitro fertilization in cattle breeding industry. This study aims to build an automatic moving stage prototype which has two degrees of freedom using hybrid stepper motor connected mechanically with rails of the microscope moving stage. Microscope stage(More)
