Abstract

Penelitian ini bertujuan mengetahui distribusi glycoconjugate yang terekspresi pada sel epitelium oviduk kancil (Tragulus javanicus). Dalam penelitian ini digunakan satu oviduk kancil yang berasal dari satu ekor kancil b etina dewasa berumur lebih dari satu tahun. Sampel difiksasi dengan larutan Bouin dan diproses menurut standar histologi sampai menjadi blok parafin dan dipotong dengan ketebalan 5 µm. Jenis lektin yang digunakan adalah biotinylated (Con A, PNA, RCA, UEA I, dan WGA) dengan dosis masing-masing sebanyak 15 µg/ml. Hasil penelitian diketahui bahwa glycoconjugate dengan residu gula galaktosa, glukosa, manosa, N-asetilgalaktosamin, N-asetilglukosamin, fukosa, dan asam sialat ditemukan pada bagian apikal sel epitel dan di dalam sitoplasma. Glycoconjugate dengan residu gula N-asetilgalaktosamin merupakan glycoconjugate yang paling banyak ditemukan di bagian apikal sel epitel dan di dalam sitoplasma dibandingkan dengan glycoconjugate dengan residu gula lainnya.

Abstract

The aim of this study was to examine the potency of fibroblast cells transdifferentiated to neuron cells in vitro. Newborn rat neuron conditioned medium (NBRN CM) was collected from neuron cells cultured with mDMEM without serum for 48 hours. Fibroblast cells were collected from fetal rat muscle treated with trypsin. Fibroblast cells were culture with 3 kind of culture medium: mDMEM + 0.01 mM          β-mercaptoethanol; mDMEM + 50% NBRN-CM and  mDMEM + 0.01 mM β-mercaptoethanol + 50% NBRN CM . As control, cells was cultured with mDMEM +10% newborn calf serum (NBCS). The addition of NBRN CM into culture medium resulted in 12.97% newborn cells in fibroblast culture medium passage I. Newborn rat neuron conditioned medium in fibroblast culture medium resulted 12.97% neuron cells at passage 1. The percentage was increased (14.60%) when β- mercaptoethanol added into medium. The same result was found at passage 3 (12.67%; 13.17%). It showed that fibroblast cells has potency to transdifferentiated into neuron cells when cultured with NBRN CM. Further research is needed to know the fibroblast transdifferentiation potency. Key words: fibroblast, transdifferentiation, conditioned medium, neuron cells, in vitro
