本研究目的是以不同晶粒大小的氫氧基磷灰石(HA)塊材做為基材，探討人類類骨母細胞(HOS)與人類纖維母細胞(HSF)初期之增殖情況。本實驗以濕式法合成HA粉末，藉由不同的製備參數：滴定速率、滴定溫度、熟化時間及不同塊材燒結溫度，並透過X光繞射(XRD)鑑定其結構及計算晶粒大小，以了解影響晶粒大小之因素。此外，利用高解析分析電子顯微鏡(HR-AEM)觀測粉末型態和利用表面粗度測定儀量測塊材表面粗糙度。實驗結果顯示，在滴定溫度25℃和80℃下製備出的HA之晶粒大小分別為11和22nm，HA塊材經燒結400、800和1200℃後，晶粒大小分別為20、32和47nm。利用MTT測量細胞增殖情況，藉以評估細胞相容性，實驗結果發現晶粒愈大之HA塊材，HOS細胞增殖情況愈好；另一方面，HSF細胞在不同晶粒大小的HA塊材上，經一、三天培養後各有不同的增殖情形，且HA基材對於HSF細胞之增殖似乎有抑制的作用，因此，綜觀上述結論，HA塊材之晶粒大小可能會影響此兩種細胞的增殖表現，也因為不同的細胞種類對於基材的反應不同，造成細胞增殖上的差異。

The purpose of the study is to investigate the influence of hydroxyapatite grain size on initial proliferation of human osteoblast-like cells (HOS) and human skin fibroblasts (HSF). In this study, HA powders were prepared using wet methods. Reactant addition rate, reaction temperatures, aging time and sintering time would be changed respectively throughout the reactant process and examined using X-ray diffraction (XRD) to identify the phase and estimate the grain size. Besides, the morphology of HA powders was displayed by Ultrahigh Resolution Analytical Electron Microscope (HR-AEM) and the surface roughness of HA bulks was evaluated by Surface Roughness Measurement Instrument. The results revealed the grain size of HA powders reacting at temperature 25 and 80℃ were 11 and 22 nm, respectively. The average grain size of HA bulks increased to 20, 32 and 47 nm when sintering at 400, 800 and 1200℃, respectively. Further, cell proliferation was measured by the Methylthiazoletetrazolium (MTT) test. The results of the study provided that HOS proliferation was significantly greater on the larger grain size of HA bulks than the smaller ones. On the other hand, HSF cells showed disparate cell proliferation on different grain size of HA bulks after culturing 1 and 3 days; moreover, HA seemed to have the function of restraining the proliferation of HSF cells. Therefore, it has been observed that HA grain size may affect the proliferation of HOS and HSF cells. Also, the cell types react distinctively according to various materials, and thus caused a variety of cell proliferation.
