可溫控和熒光檢測(cè)
實(shí)時(shí)變形細(xì)胞計(jì)數(shù)和同時(shí)熒光檢測(cè):
- 熒光模塊使得該系統(tǒng)不再只是附加了一個(gè)額外的細(xì)胞力學(xué)檢測(cè)通道的流式細(xì)胞儀。它成為了生命科學(xué)實(shí)驗(yàn)室的得力工具 - 提供了更多視角來(lái)解決科學(xué)問(wèn)題。在生物學(xué)研究中通常使用熒光流式細(xì)胞儀來(lái)鑒定和定量細(xì)胞和細(xì)胞過(guò)程。使該系統(tǒng)集熒光流式細(xì)胞儀和實(shí)時(shí)變形的優(yōu)點(diǎn)于一身,形成了實(shí)時(shí)熒光形變細(xì)胞儀。光片激發(fā)設(shè)計(jì)可實(shí)現(xiàn)三通道1D熒光成像。除了所有實(shí)時(shí)變形參數(shù)外,系統(tǒng)還會(huì)分析熒光信號(hào)實(shí)時(shí)得到峰圖,速度可達(dá)每秒1000個(gè)細(xì)胞。也可在實(shí)驗(yàn)后處理保存的原始熒光數(shù)據(jù),以針對(duì)特定的問(wèn)題和需 求修改處理方法。
1)根據(jù)表面marker鑒定血細(xì)胞:
熒光模塊可檢測(cè)和鑒定同一樣品中的三種不同熒光。利用標(biāo)記的表面熒光蛋白可同時(shí)實(shí)現(xiàn)細(xì)胞鑒定和力學(xué)性質(zhì)及形態(tài)性質(zhì)測(cè)量。 下圖為 G-CSF動(dòng)員的外周血樣品細(xì)胞群體。 標(biāo)記后的細(xì)胞表面markers CD3-FITC (T-cells), CD34-PE (造血干細(xì)胞)和CD14-APC(單核細(xì)胞)熒光強(qiáng)度檢測(cè) 揭示了各細(xì)胞類(lèi)型所具有的不同力學(xué)性質(zhì)。- 2)一維熒光成像:
熒光模塊在激發(fā)光路徑中產(chǎn)生一束受限光片,穿過(guò)流道,細(xì)胞會(huì)經(jīng)過(guò)一束很窄的激發(fā)光幕。這樣可以進(jìn)行1D熒光成像,例如可用于解析沿流動(dòng)方向的熒光標(biāo)記結(jié)構(gòu)的側(cè)向分布。檢測(cè)到的熒光峰值帶有很多重要信息。熒光標(biāo)記的胞內(nèi)結(jié)構(gòu)(如細(xì)胞核)會(huì)顯示窄峰,而胞質(zhì)會(huì)顯示出更寬的峰。不同分裂期細(xì)胞中標(biāo)記的組蛋白也會(huì)呈現(xiàn)出不同的峰圖.
加熱模塊 - 溫度控制
加熱模塊實(shí)現(xiàn)了生理溫度下的測(cè)量。加熱模塊帶有一個(gè)300 W的加熱器和幾個(gè)靜默通風(fēng)機(jī)來(lái)有效混合熱空氣。靠近樣品處有一個(gè)傳感器和一個(gè)控制單元,用以地將溫度控制在所需值。系統(tǒng)的空氣循環(huán)系統(tǒng)非常高效,當(dāng)進(jìn)行開(kāi)放操作(如更換樣品)后可以迅速恢復(fù)溫度。
高速攝像
該成像模塊是款高速明場(chǎng)攝像顯微鏡,使用同步化微秒高強(qiáng)度LED光源減輕運(yùn)動(dòng)模糊,可進(jìn)行極慢運(yùn)動(dòng)攝影.每秒可記錄500幅全幀圖像或10000幀小區(qū)域圖像
越來(lái)越多的研究表明,機(jī)械力(Mechanical Forces)是機(jī)體生長(zhǎng)發(fā)育、結(jié)構(gòu)重建以及功能維持的重要因素,也與疾病的發(fā)生發(fā)展密切相關(guān)。力學(xué)刺激(Mechanical Stimulation)會(huì)對(duì)細(xì)胞的粘附、鋪展、遷移、增殖和分化等行為有著重要的影響,力學(xué)表型(Mechanical phenotype)的改變也可用來(lái)定量檢測(cè)、評(píng)價(jià)細(xì)胞的生物學(xué)功能。力學(xué)生物學(xué)(Mechnobiology)研究對(duì)深入揭示疾病機(jī)理、發(fā)展新的診斷治療方法具有重要意義,還可以為生物材料、再生醫(yī)學(xué)、藥物篩選等應(yīng)用研究提供新思路、新工具。由于細(xì)胞內(nèi)在的生物復(fù)雜性及微納米尺度的制約,如何實(shí)現(xiàn)細(xì)胞及亞細(xì)胞水平上力學(xué)信息的實(shí)時(shí)、原位、動(dòng)態(tài)探測(cè)和操控是力學(xué)生物學(xué)中的挑戰(zhàn)性的問(wèn)題之一。
