在生醫研究上使用光學顯微系統觀察生物樣本的時候，需要能夠快速並且穩定的獲取即時資訊以及提供樣本的完整性，而結構照明顯微術 (Structured Illumination Microscopy, SIM) 除了能夠提供光學切片的功能和有著不錯的影像對比度之外，還可以穩定並且快速的取得即時影像，因此成為了一種能夠提供生醫研究上觀察樣本的工具。 以往使用光學顯微系統觀察毛囊的不同生長週期的型態時，需要將許多隻經過密蠟除毛後的小鼠在不同的毛囊生長週期時間上，將其背部一部份的皮膚切下並且犧牲掉小鼠，接下來再把皮膚毛囊幹細胞染上不同的螢光標記並做成樣本，藉此來觀察不同時間毛囊的生長週期狀態，但是這樣的實驗過程中沒有辦法觀察由同一隻小鼠毛囊生長周期變化的連續性，而且樣本染色的成功與否也會影響觀察的方向性和正確性，最後小鼠的犧牲也會造成小鼠資源浪費並且無法再次利用。 本論文以綠螢光蛋白(Green Fluorescent Protein, GFP)基因轉殖的小鼠做為樣本，其背部經過密蠟除毛使所有毛囊同步進入毛囊生長的休止期，利用以數位微型投影機 (Digital Light Projector, DLP) 做為系統光源的結構造明顯微系統來進行活體小鼠的觀察，實驗將持續一整個毛囊生長週期的循環時間觀察毛囊生長周期過程中不同的型態樣貌。 ;In biomedical research, when using microscope system to observe biological sample, it is necessary to have fast and stable data acquisition with completeness of samples. Structured illumination microscopy not only can provide optical sectioning and nice image contrast, but also capture image fast and stable. These advantages make structured illumination microscopy become a popularity-used system for biomedical research. When observing hair follicles with optical microscopy system in the past, different mice have to be waxed and sacrificed to get back skin samples at different stages of the hair growth cycle. The hair follicle stem cells of the samples should be strained with dye of fluorophores to enhance their contrast for observation. However, with these process, the observation can-not be focused on the same mouse in a complete growth cycle and the staining process plays a key role in the sample completeness and data accuracy. In this paper, green fluorescence protein (GFP) transgenic mice were used as the specimens. The mice were waxed to synchronize all hair follicles into anagen state of the growth cycle. By using the structured illumination microscopy system based on a digital light projector to observe the mice hair follicle in vivo. The observation will be last for a complete hair follicle growth cycle to long-term monitior the hair follicle stem cell morphology at different stages of the growth cycle.
