BACKGROUND Extending the period of in-vitro culture to the blastocyst stage may improve implantation rates in IVF treatment. Recognition of the dynamic nature of early embryo metabolism has led to the development of commercially available sequential culture systems. However, their improved efficacy over monoculture systems remains to be demonstrated in prospective studies. METHODS Embryos obt...
Background: Primary culture takes place following the cell isolation from tissues. Isolation and culture of melanocytes based on their roll in the protection of body against hazardous sun rays, production of skin, cornea and hair color is really important. This study was done to set isolation, culture and proliferation of melanocytes from children foreskin and adult eyelashes, and also comparis...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
This study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. One-cell mouse embryos were obtained from NMRImice after superovulation by an intraperitoneal injection of 5 IU equine chorionic gonadotrophin (eCG)followed 48 hrs later by 5 IU human chorionic gonadotrophin (hCG). Mouse embryonic fibrobla...
STUDY QUESTION Do culture media influence birthweight of children born after IVF? SUMMARY ANSWER Some studies have observed a significant effect of culture media on birthweight, while others have not, but since most studies compared different culture media, conventional meta-analysis was not possible. WHAT IS KNOWN ALREADY Animal studies suggest that in vitro culture of embryos can have a s...
Background The aim of this study was to establish a cell-free sequential culture system that can support high levels of in vitro embryo development and blastocyst formation from bovine zygotes. To this end, this investigation was carried out to evaluate the effects of glucose, serum and EDTA on bovine zygote in vitro development. MaterialsAndMethods Bovine presumptive zygotes were derived from ...
The zinc-binding protein metallothionein (MT) is associated with resistance to apoptosis. We examined whether MT regulates the zinc-dependent antiapoptotic transcription factor nuclear factor B (NFB), which is up-regulated under many conditions that lead to elevated MT expression. NFB protein levels and NFB-dependent reporter gene activity were examined in clonal MT( ) (MT-WT) and MT( ) (MT-KO)...
BACKGROUND Mycobacterial culture and identification provide a definitive diagnosis of TB. Culture on Löwenstein-Jensen (L-J) medium is invariably delayed because of the slow growth of M. tuberculosis on L-J slants. Automated liquid culture systems are expensive. A low-cost culturing medium capable of rapidly indicating the presence of mycobacteria is needed. The aim of this study was to develop...
Kanwar, Yashpal S., Kosuke Ota, Qiwei Yang, Jun Wada, Naoki Kashihara, Yufeng Tian, and Elisabeth I. Wallner. Role of membrane-type matrix metalloproteinase 1 (MT-1-MMP), MMP-2, and its inhibitor in nephrogenesis. Am. J. Physiol. 277 (Renal Physiol. 46): F934–F947, 1999.— Extracellular matrix (ECM) proteins, their integrin receptors, and matrix metalloproteinases (MMPs), the ECMdegrading enzyme...
Pyricularia oryzae (Tel. Magnaporthegrisea) is currently used as a fungal model for plantmicrobeinteraction studies as well as an indicative model for anticancer drug discovery. Thepresent study introduces the optimal condition in which P. oryzae grows and sporulates beston common culture media. We have considered three fungal culture media, i.e. PDA, PCA andWA, based on which P. oryzae sporula...
