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...

Cell Suspension Culture, Somatic Embryo Genetic and Synthetic Seed Production in Different Cultivars of Potato

genetic and phenotypic parameters related to production traits, udder conformation and somatic cell count for the iranian holstein cows were estimated. monthly records of somatic cell counts (scc) were primarily transformed into somatic cell scores (scs) and the the average level of lactation period, with correction for milk volume, was calculated. by use of these estimates an udder health inde...

Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...

A yeast cell culture approach mimics the benefits of somatic hypermutation to accelerate discovery desirable antibodies.

This experiment was aimed to study the association between the DGAT1 K232A polymorphism and milk production traits and somatic cell score (SCS) in Iranian Holstein dairy cows. The records of 408 animals from five dairy herds were randomly identified and then genomic DNA was extracted from blood using the modified-salting method described by Miller. RFLP-PCR was performed to obtain all the polym...
