In Urodele amphibians, the tail regenerates after section. This regeneration, including tissues as different as bone (vertebrae), muscle, epidermis and central nervous system (spinal cord), was studied in adult Pleurodeles sent aboard the russian sat

Pleurodeles waltl , an Urodele amphibian is proposed as a model for space biology studies. Our laboratory is developing three types of experiments in space using this animal: 1. 1) in vivo fertilization and development (“FERTILE” project); 2. 2)i

The experiments reported here were undertaken to investigate the influence of some methodological factors on the radiosensitivity of the mouse zygote. The following factors were studied: 1) the use of natural or hormone-stimulated ovulation; 2) the p

The objectives of this experiment are to perform natural fertilization and to achieve embryonic development in microgravity. Pleurodeles waltl, an urodele amphibian, is considered by CNES and NASA to be suitable experimental material for achieving in

The effect of caffeine was studied on mouse zygotes blocked in the G2 phase of the first cell cycle after X-irradiation. Caffeine (2 mM) effectively reversed the G2 arrest when zygotes were incubated in its presence at the time when first mitosis nor

The initial slope of the survival curve, which is a characteristic of each tumor cell line, varies with the histological group of the tumor. It is one of the factors on which clinical radioresponsiveness depends. The DNA dependant DNA polymerase inhi

Female mice of the BALB/c strain were superovulated, mated with males of the same strain, and irradiated with 1 Gy of X-rays at hourly intervals during the first cell cycle of the embryos. Two types of effects were found in the embryos, depending on

Before an oxic cell sensitizer such as beta-ara A (a DNA-dependent DNA polymerase inhibitor) can be used in cancer treatment, it is essential to know both the influence of this type of drug on certain critical normal tissues and the role of prolifera

After X-irradiation at pronuclear stage, mice eggs from certain strains are reversibly blocked in G2 phase of the first cell cycle. However, evolution of polypeptide synthesis takes place in a normal way, except for three polypeptides sets of 30, 35

Mouse eggs from the BALB/c strain present a peculiar sensitivity to X irradiation: when they are irradiated in the oviduct between 17 and 24 hours after HCG injection, a proportion of them, increasing with the dose, are reversibly blocked at the one-
