Petaka 細(xì)胞培養(yǎng)系統(tǒng)中Micro-tubular gas diffusion channel,是Celartia公司的技術(shù),自動(dòng)平衡培養(yǎng)基質(zhì)中的溶解氧含量——45mmHg,嚴(yán)格模擬細(xì)胞的天然生長(zhǎng)條件。同時(shí)Petaka 細(xì)胞培養(yǎng)系統(tǒng)可根據(jù)培養(yǎng)細(xì)胞的類型,耗氧情況,從而減少培養(yǎng)系統(tǒng)中的氧氣含量,比如常規(guī)的21%的氧氣含量降低至5%或2%。
觀點(diǎn)一: 京都大學(xué)教授山中伸彌等人在iPS細(xì)胞研究過(guò)程中,發(fā)現(xiàn)機(jī)體內(nèi)的干細(xì)胞總是集中于氧氣相對(duì)少的地方。于是,他們?cè)诶萌梭w皮膚細(xì)胞培養(yǎng)iPS細(xì)胞時(shí)把培養(yǎng)環(huán)境的氧濃度從通常的21%降到5%,發(fā)現(xiàn)iPS細(xì)胞的生成效率可提高到原來(lái)的2.5倍至4.2倍。
觀點(diǎn)二: 低氧是生物體常見(jiàn)的一種生理和病理現(xiàn)象,不同組織的細(xì)胞生長(zhǎng)在不同的氧濃度下,在探討氧環(huán)境是否影響相關(guān)干細(xì)胞分化上值得我們干細(xì)胞工作者們做深入研究,尤其是在胚胎發(fā)育過(guò)程中氧濃度的變化對(duì)相關(guān)組織的形成與發(fā)育研究在不久的將來(lái)定會(huì)有重大的突破。
觀點(diǎn)三: 低氧環(huán)境對(duì)胚胎早期發(fā)育過(guò)程影響很大,像體外培養(yǎng)的細(xì)胞(常壓/常氧),與體內(nèi)相比,表觀修飾發(fā)生了巨大變化。
PetakaG3™ LOT (Low Oxygen Transfer)
The cell culture device PetakaG3 is an innovative bioreactor designed for mammalian cell culture in physiologic tissue conditions. The distinctive feature of PetakaG3 is that being a disposable device incorporates an automatic gas diffusion control system (AGD-CS) that works interactively with the cells growing and living inside, WITHOUT HYPOXIA CAMBERS, GLOVE BOXES OR THREE-GAS INCUBATORS
For cells cultured in PetakaG3 and incubated in regular 21% oxygen atmosphere the AGD-CS provides:
1) Media dissolved oxygen concentration within the limits of the physiologic oxygen tensions in physiologic tissues (from 75 mmHg down to 15 mmHg) monitorable with a dissolved oxygen fluorescent sensor dot. Because this advanced trait PetakaG3 is the safest, smallest, unique portable disposable hypoxia chamber, also available with integrated DO sensor.
Average DO = 1 mg/L (0.5 to 1.1 mg/L depending on cell type), equivalent to average 22.7 mmHg (Torr) in tissues or equivalent to average 3.11 %O2 in hypoxia chambers.

2) Media dissolved CO2 concentration, enough to maintain a physiologic pH without external extra-supply of carbon dioxide gas.
3) Controlled media evaporation even at 2% to 10% atmospheric Relative Humidity (RH).
PetakaG3 allows cultures of two different cell types in the same device. Both cell layers are separated by 3mm of media, which is appropriate to study intercellular interactions through diffusible factors and exosome exchange. PetakaG3 is ideal for transfection of both cell layers with two different gene constructs in the same device with negligible cross transfection
Global specifications of PetakaG3 LOT:
- It acts as an independent hypoxia chamber between 1% and 21% Oxygen. Medium Dissolved Oxygen auto-controlled (O2PP between 2 and 50 mmHg)
- No additional CO2 required for any type of media, although the PetakaG3™device can also be used in CO2 incubators
Humidity autocontrolled, no added humidity required (not influenced by environment)
- The most secure cell culture device against contamination (no caps, no openings)
- Designed to transport live cells without requiring freezing and dry ice
- Optimizes media and growth factor supplies
- Can provide up to 15 times more cell culture surface area per incubator capacity
- Both surfaces may be viewed using any type of light microscope
- In vitro cell pause or dormancy is easily accomplished
- Allows storage of pre-filled units that are ready to host cells
- Easy to handle. It operates in any position. Compley safe & versatile
- Each Petaka is individually bar coded for easy tracking.
