HiPS stem cells are commonly used for the study of medical disorders. Thelaboratory in which this study was conducted uses these cells for examining the treatment and cureof neurodegenerative diseases. Bone regeneration poses the greatest challenge for an oral surgeonboth in terms of increased implant osseointegration and reducing bone healing times. The aim ofthis study was to validate the protocol in the literature to produce and then test in vitro osteoblastswith different nanomaterials to simulate bone regeneration.
hiPS clones (#2, #4, and #8)were differentiated into an osteoblast cell culture tested for alizarin red staining and for alkalinephosphatase testing at 14, 21 and 28 days, after the cells were plated.
The cells showeddiffuse positivity under alizarin red staining and the alkaline phosphatase (ALP)-test, showingsmall formations of calcium clusters.
Despite the limitations of our study, it is a startingpoint for further protocols, laying a solid foundation for research in the field of bone regenerationthrough the use of stem cells. .
HiPS 干细胞常用于医学疾病的研究。本研究所在使用这些细胞来研究神经退行性疾病的治疗和治愈方法。骨再生对口腔外科医生来说是最大的挑战,既需要增加植入物的骨整合,又需要减少骨愈合时间。本研究的目的是验证文献中的方案,然后用不同的纳米材料在体外培养成骨细胞,以模拟骨再生。
将 hiPS 克隆 (#2、#4 和 #8)分化为成骨细胞培养物,在细胞接种后第 14、21 和 28 天,用茜素红染色和碱性磷酸酶 (ALP) 检测进行测试。
细胞在茜素红染色和碱性磷酸酶 (ALP) 检测下呈弥漫性阳性,显示出钙簇的小形成。
尽管我们的研究存在局限性,但它是进一步研究方案的起点,为通过干细胞进行骨再生领域的研究奠定了坚实的基础。
