Somatic cell parasitism and the evolution of somatic tissue compatibility.
نویسنده
چکیده
Selection pressures proposed to account for the convergent evolution of self/not-self recognition systems in lower organisms include defense against microbial parasites and somatic cell variants. Direct support for the existence of somatic cell parasites in natural populations has been lacking. I here report the occurrence of a somatic cell parasite in the cellular slime mold Dictyostelium mucoroides and discuss the implications of this phenomenon to the evolution of mechanisms of somatic tissue compatibility.

The Effect of Different Somatic Cell Levels on Calcium and Phosphorus Contents of Milk
ABSTRACT: Mastitis is an inflammatory reaction of the mammary tissue in response to the introduction and multiplication of pathogens and is characterized by increasing somatic cell count (SCC) in milk. The main objective of present study is to assess the probable associations between somatic cell (SC) levels and calcium and phosphorus and ratio of Ca/P in raw milk. Milk samples were collected f...
متن کاملSomatic Embryogenesis: An Alternative Method for in vitro Micropropagation
Plant tissue culture is an alternative method of commercial propagation and is being used widely for the commercial propagation of a large number of plant species, including many medicinal plants. Somatic embryogenesis is a process by which asexual or somatic cells are induced to form embryos in culture. Somatic embryogenesis is a multi-step regeneration process starting with formation of pro-e...

The objective of this study was to analyze the association of somatic cell score (SCS) with milk, fat and protein yields across parities. Records of production traits and somatic cell counts (SCC) from first, second and third parity that were collected by the Animal Breeding Center of Iran from 1993 to 2010 were used.All animals were grouped into six classes according to SCC and production trai...
متن کاملP-115: Melatonin Increases Developmental Rate of In Vitro Mouse Somatic Cell Nuclear
Background: The beneficial effect of supplementing culture medium with melatonin has been reported during in vitro embryo development of species such as mouse, bovine and porcine. However, the effect of melatonin on the mouse somatic cell nuclear transfer remained unknown. Materials and Methods: In this study, we assessed the effects of various concentrations of melatonin (10-6 to 10-12 M) on t...
متن کاملI-8: Somatic Cell Nuclear Reprogramming byMouse Oocytes Endures Beyond ReproductiveDecline
Background: The mammalian oocyte has the unique feature of supporting fertilization and normal development while being able of reprogramming the nuclei of somatic cells towards pluripotency, and occasionally even totipotency. Whilst oocyte quality is known to decay with somatic ageing, it is not a given that different biological functions decay concurrently. In this study, we tested whether ooc...
