Abstract The existence of European ash ( Fraxinus excelsior L.) is threatened by fungus-induced dieback. It essential to find effective methods multiply genotypes resistant dieback while preserving the genetic diversity these tree populations. In this paper efficient method for production seedlings using indirect auxiliary organogenesis with multi-factor analysis its effectiveness presented. Pr...

the old wishes of people were to regenerate lost tissues of periodontium that this fact is achieved by gen and cell therapy .periodontal disease is a chronic inflammation around the tooth by microbes that causes destruction of supporting structure of tissue of tooth such as alveolar bone, cementum and periodontal ligament. for treatment of periodontal diseases we can use the biomaterials which ...

background: the basal medium that supports isolated mouse oviduct (imo) is important for supporting embryo development and quality. methods: the culture of ovine ivm/ivf zygotes was done in imo using sofaacibsa and sofaabsa as basal medium of imo and in sofaabsa alone as control. for preparation of imo mature inbred strain c57bl/6 female mice were synchronized and mated with vasectomized males....

Background: It was reported in a literature that approximately one third of the 4-cell stage embryos did not exhibit a tetrahedral shape. Non-tetrahedral embryos showed a lower in vitro developmental potential than tetrahedral embryos. Recently vitrification technology has been widely employed for embryo cryopreservation. The objective of this study was to prove our hypothesis that vitrified - ...
