Since each laboratory used different culture methods, the productivity of the different cultures may vary. Therefore, the purpose of this study is to optimize a stable and reliable hucMSC culture procedure. Methods: Mesenchymal stem cells derived from human umbilical cord were isolated and cultured in different culture medium. By comparing the morphology, passage, proliferation and using flow cytometry to detect the immunophenotypes of the cells, optimized cultural method was selected.Results: By comparison of the time of cells migrating out from the tissue, cell growth status, cell number and expression of CD90 andCD73 of the hucMSCs, we found that X-VIVO15+10% fetal bovine serum group, X-VIVO15+2% fetal bovine serum and 2% UltroserG group, and MSC basal medium+UltraGRO-Advanced group had an earlier migration time from the umbilical cord and shorter confluence time to cover 80%-90% of the cuturing flask. The Huc-MSCs cultured with MSC basal medium+2% UltraGRO-Advanced group revealed the fastest proliferation. The expression of CD90 and CD73 in Huc-MSCs cultured with MSC basal medium+2% UltraGRO-Advanced group were above 90%, while the expression of CD90 and CD73 in other groups were below 90%. The expression of CD34 and CD45 surface antigens were low in huc-MSCs from all the groups.Conclusion:In summary, MSC basal medium-UltraGRO-Advanced group was the optimal culture medium for human umbilical cord mesenchymal stem cells.展开更多

Scott （2000） stresses the requirement of aesthetic and semiotic content in a creative product, instead of creativity. But, how many of retailers and salespersons in heritage product believe the semiotic as knowledge to present the product and opportunities in their selling？ According to Kotler （2000） a good personal selling will provide a detailed explanation or demonstration of the product. The message can be varied by the salesperson to fit the motivations and interests or each prospective customer. So, the purpose of this paper is to closely examine the level of awareness among retailers and salesperson toward the important of semiotic knowledge as part of strategic persuasion in a selling process. This survey study will develop a sample among retailers and salesperson in Kuala Terengganu as a respondent who give the feedback to fulfill the research questions.展开更多

An avalanche is then regarded as a first-return random walk process in a one-dimensional lattice. We assume that the variation of the number of active sites has three possibilities in each update： to increase by 1 with probability f1, to decrease by 1 with probability f2, or remain unchanged with probability 1 - f1 - f2. This mimics the dynamics in the system. Power-law distributions of the lifetime are found when the random walk is unbiased with equal probability to move in opposite directions. This shows that power-law distributions in self-organized criticality may be caused by the balance of competitive interactions.展开更多
