calcium crystals are evident in many parts of anther. there is little literature about differentiationof crystal-containing cells and crystal formation during anther development. petunia hybrid grandifloraflower buds collected at different developmental stages were fixed and studied. the results revealed thatyoung anthers are tetrasporangiate and in each of the four corners, the primary parieta...

introduction: inactivated influenza vaccines are traditionally produced in chicken embryonated eggs but its limitations in producing the required doses in pandemic outbreaks quickly enough has made searching for alternative modes of production necessary. the use of cell culture-based vaccine production is one way of overcoming the limitations of the egg-based method and securing a more rapid re...

seth4 coding sequence with 2013 bp is a member of gene family expressed in gametophytic tissues of arabidopsis thaliana. this fragment was pcr amplified using kod hi fi dna polymerase enzyme. this fragment was cloned into pgbkt7 bate vector and transformed e. coli dh5? cells containing vector were selected on lb medium containing kanamycin. finally, pgbkt7-seth4 bate was transformed into yeast ...

objective: in this investigation murine embryonic stem (es) cells were differentiated into endothelial cells. materials and methods: murine es cells (cce cell line) exposed to alpha-mem medium containing 10% fbs for 4 days. then obtained flk-1 (flk-1: vascular endothelial growth factor receptor 2) positive cells were cultuted in endothelial growth medium-2 (egm-2) until the last day of experime...

a series of sorbents containing various amounts of borate groups were prepared by chemical immobilization ofp-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. it was found thatbaker's yeast cells selectively adhered to these supports. yeast cells stained with procion red he-3b formeddenser and more stable layer on the copolymer-grafted supports compared onto ...
