Real time-qPCR is the most reliable method for evaluation of mRNA expression levels. However, to obtain accurate results, selection of suitable reference genes is necessary for normalizing the real-time qPCR data. The aim of this research was to validate the expression stability of three potential reference genes (ACTB, GAPDH and UXT) in milk somatic cells of Holstein dairy cattle under differe...

Background: For several years, mammalian cloning by splitting an early embryo or nuclear transfer into oocytes method has been successfully performed. Cloning is now also possible using adult somatic cells. Although it has now been 15 years since the first cloned mammals were generated from somatic cells using nuclear transfer (NT), the success rate for producing live offspring by cloning is lo...

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...

Purpose: Despite remarkable progresses have been achieved in the field of somatic cell nuclear transfer (SCNT), there is little information regarding the effect of donor cell type on the efficiency mammalian somatic cell cloning in vitro. This study compared in vitro developmental competency of sheep enucleated oocytes reconstructed with either fibroblast or cumulus cells. Material and methods...

background: recognition of helminth-derived pathogen associated molecular patterns (pamps) by pattern recognition receptors (prrs), including toll like recep­tors (tlrs) is the first step towards initiating anti–helminth immune re­sponses. methods : using somatic antigens of ostertagia occidentalis, an important abomasal parasite of ruminants, the expression of ovine tlr2 and tlr4 in peripheral...

Somatic embryogenesis is a developmental process during which plant somatic cells, under in vitro conditions, produce embryogenic cells that develop into embryos. an efficient method clonal propagation of plants. Mature embryos were used as explant source for callus formation and the produced compact, healthy most mature induced callus. showed similar morphologically to their non-somatic counte...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...

Abstract An understanding of the factors behind evolution multicellularity is one today’s frontiers in evolutionary biology. This because multicellular organisms are made subset cells with capacity to transmit genes next generation (germline cells) and another responsible for maintaining functionality organism, but incapable transmitting (somatic cells). The question arises: why do somatic sacr...

clinical application of embryonic stem (es) cells faces difficulties regarding tissue rejection as well as ethical limitations. one solution for these issues is to reprogram somatic cells by the injection of their nucleus into an enucleated oocyte or zygote. however, technical complications and ethical considerations have impeded the therapeutic implications of this technology. an approach whic...
