Human   adult skin fibroblasts (hASFs) were isolated from donated adult dermis   tissues that obtained with informed written consent.

人成人皮膚成纖維細(xì)胞 (hASF) ，是從經(jīng)知情書(shū)面同意的捐贈(zèng)者采集的脂肪組織分離的。

1)   The tissues (0.5-1 cm2) were washed twice with PBS containing 2%   penicillin-streptomycin, minced by scissors to 0.5-1 mm2 pieces.

用含有 2% 青霉素-鏈霉素的 PBS 洗滌組織 (0.5-1 cm²)兩次, 用剪刀切成 0.5-1 mm² 的塊。

2)   The pieces were placed in the 100-mm cell culture dish and 1 drop of 15%   FBS-DMEM medium was put onto each piece of tissue.

8)   We passaged the hASFs both for reprogramming and expansion in the same way to   hADSCs mentioned above.

以與上述hADSC相同的方式將 hASF 傳代以進(jìn)行重編程和擴(kuò)增到。

Commercial   human adult dermal fibroblasts (Lonza-CC2511) and ADSCs (Lonza-PT5006) were   also cultured in Mesenchymal Stem Cell Growth Medium 2 and passaged both for   reprogramming and expansion in the same way to hADSCs mentioned above.

商業(yè)人成人真皮成纖維細(xì)胞 (Lonza-CC2511)和 ADSC (Lonza-PT5006)也在MSCGM2中培養(yǎng), 并以與上述hADSC相同的方式傳代以進(jìn)行重編程和擴(kuò)增。

We   recommended to use the primary isolated hADSCs (passages 2-4) for the   induction of hCiPSCs. If the primary hASFs were used, the cells passages   between 2 to 4 were recommended. For these commercially available hADSCs or   hASFs, cultivating two passages in Mesenchymal Stem Cell Growth Medium 2 will   help to improve the state of these cells and reprogramming efficiency. The   longer passaged cells can be also used for the induction of hCiPSCs, but with   quite reduced induction efficiency. Long term passaged commercial cell lines   (IMR90 and BJ, etc.) are not recommended for the induction of hCiPSCs.

建議使用原代第2-4代分離的hADSC來(lái)誘導(dǎo) hCiPSC。如果使用原代 hASF,細(xì)胞傳代 2 - 4 次（對(duì)于市售 hADSC 或 hASF, MSCGM2中培養(yǎng)兩次傳代將有助于改善細(xì)胞的狀態(tài)和重編程效率）。較長(zhǎng)傳代的細(xì)胞也可用于誘導(dǎo) hCiPSC, 但誘導(dǎo)效率低。故不建議將長(zhǎng)期傳代的商業(yè)細(xì)胞系 (IMR90 和BJ等)用于誘導(dǎo) hCiPSC。

第三階段的誘導(dǎo)培養(yǎng)基組分

KnockoutTM   DMEM supplemented with 2% B27 supplement, 1% GlutaMAX, 1% NEAA, 1%   Penicillin-Streptomycin, 5% Knockout Serum Replacement (KSR), 50 μg/ml Vc2p,   20 ng/mL Recombinant Human Heregulinβ-1 (HRG) and the small molecules   CHIR99021 (1 μM), Y-27632 (10 μM), PD0325901 (1 μM), SB590885 (0.5 μM).   During the induction process of stage III, VPA (1000 μM), Tranylcypromine (10   μM), DZNep (0.2 μM), and EPZ5676 (2 μM) were included in the medium for the   first 4 days. Subsequently, VPA (500 μM) was included in the next 4 days   while Tranylcypromine, DZNep, and EPZ5676 were removed. The stage III   induction medium without VPA, Tranylcypromine, DZNep, or EPZ5676 could be   applied for additional 2-4 days to allow the primary hCiPSC colonies to grow   larger.

補(bǔ)充有 2% B27 補(bǔ)充劑、1% GlutaMAX、1% NEAA、1% 青霉素-鏈霉素、5% 敲除血清替代物 (KSR)、50 μg/mL Vc2p、20 ng/mL 重組人 Heregulinβ-1 (HRG)和小分子 CHIR99021 (1 μM)、Y-27632 (10 μM)、PD0325901 (1 μM)、SB590885 (0.5 μM)的敲除 DMEM。在第三階段的誘導(dǎo)過(guò)程中, 前 4 天將 VPA (1000 μM)、反苯環(huán)丙胺(10 μM)、DZNep (0.2 μM)和 EPZ5676 (2 μM)包含在培養(yǎng)基中。

隨后, 在接下來(lái)的 4 天內(nèi)加入 VPA (500 μM), 同時(shí)去除反式環(huán)丙胺、DZNep 和 EPZ5676。而不含 VPA、反式環(huán)丙胺、DZNep 或 EPZ5676 的 第三階段誘導(dǎo)培養(yǎng)基可以再施用 2-4 天, 以使原代 hCiPSC集落更大。

Please   prepare each medium freshly and shake well after configuration and before   use. Prepared induction media can be stored at 4℃ for up to two weeks.

備注：請(qǐng)采用新鮮制備每種培養(yǎng)基, 并在配置后和使用前搖勻（制備誘導(dǎo)培養(yǎng)基可4℃儲(chǔ)存長(zhǎng)達(dá)兩周）。

1.   hADSCs and hASFs were seeded in high-glucose DMEM supplemented with 15% FBS   at a density of 1 x 104 cells per well of a 12-well plate or 5-6 x 103 cells   per well of a 24-well plate, and would be changed into freshly prepared stage   I induction medium after 12-24h. Please ensure that the cell density is   appropriate and cells are evenly attached to the bottom of each well. An   appropriate cell density seeded at day-1 is important for the reprogramming   efficiency and induction of the epithelial-like cells in stage I. We highly   recommend to optimize the cell density seeded at day-1 when the percentage or   area of epithelial-like cells is too low at the end of stage I.

hADSCs 和 hASFs 接種在補(bǔ)充有 15% FBS 的高葡萄糖 DMEM 中, 密度為 12 孔板每孔 1×10⁴ 個(gè)細(xì)胞或 24 孔板每孔 5-6×10³ 個(gè)細(xì)胞, 12-24 小時(shí)后更換為新鮮制備的第一階段誘導(dǎo)培養(yǎng)基。

確保細(xì)胞密度適宜,且細(xì)胞均勻地附著在每個(gè)孔的底部。在第 1 天接種的適當(dāng)細(xì)胞密度對(duì)于第一階段上皮樣細(xì)胞的重編程效率和誘導(dǎo)很重要。強(qiáng)烈建議在第一階段結(jié)束時(shí)上皮樣細(xì)胞的百分比或面積過(guò)低時(shí)優(yōu)化第 1 天接種的細(xì)胞密度。

2.   For stage I induction, single layer epithelial-like cells would emerge at day   4-6. When the epithelial-like cells reach ～100% confluence (usually after 8-10 days’ stage I   induction for hADSCs and 9-16 days for hASFs). Change the medium into freshly   prepared stage II induction medium. Cells at the end of stage I may not be   firmly attached, so be gentle when changing the medium.

對(duì)于第一階段誘導(dǎo), 單層上皮樣細(xì)胞將在第 4-6 天出現(xiàn)。當(dāng)上皮樣細(xì)胞達(dá)到近100%融合度時(shí) (通常在 hADSC 的第一階段誘導(dǎo) 8-10 天和 hASF 的第一階段誘導(dǎo) 9-16 天后)，將培養(yǎng)基更換為新鮮制備的第二階段誘導(dǎo)培養(yǎng)基。第一階段結(jié)束時(shí)的細(xì)胞可能沒(méi)有牢固附著, 因此更換培養(yǎng)基時(shí)要輕柔。

3.   For stage II induction, multi-layered cell colonies appeared after 4-6 days   treatment and these cell colonies would continually grow larger. In the last   four days of stage II, due to the strong proliferation of cells, the medium   can be changed every two days, or you can add the same volume of stage II   medium to the original well on the penultimate day. It is normal that there   is cell death in late stage II.

對(duì)于第二階段誘導(dǎo), 處理 4-6 天后出現(xiàn)多層細(xì)胞集落, 這些細(xì)胞集落會(huì)不斷變大。在第二階段的最后 4 天, 由于細(xì)胞增殖較強(qiáng), 可以每?jī)商旄鼡Q一次培養(yǎng)基, 也可以在倒數(shù)第二天向原始孔中加入相同體積的第二階段培養(yǎng)基（第二階段晚期有細(xì)胞死亡是正常的）。

4.   Change the medium into freshly prepared stage III induction medium after 8-12   days’ treatment of stage II medium when the colonies grow larger. The   induction days of stage II is important for the induction efficiency of   hCiPSCs. You can switch stage II to stage III after 8, 10 or 12 days of stage   II induction, and compare efficiency.

當(dāng)細(xì)胞集落變大時(shí), 在第二階段培養(yǎng)基處理 8-12 天后, 將培養(yǎng)基更換為新鮮制備的第三階段誘導(dǎo)培養(yǎng)基。第二階段的誘導(dǎo)天數(shù)對(duì) hCiPSC 的誘導(dǎo)效率很重要。您可以在第二階段誘導(dǎo) 8、10 或 12 天后將第二階段切換到第三階段, 并比較效率。

5.   For stage III induction, VPA (1000 μM), Tranylcypromine (10 μM), DZNep (0.2   μM), and EPZ5676 (2 μM) were included in the induction medium for the first 4   days. Subsequently, VPA (500 μM) was included in the next 4 days while   Tranylcypromine, DZNep, and EPZ5676 were removed. The stage III induction   medium without VPA, Tranylcypromine, DZNep, or EPZ5676 could be applied for   additional 2-4 days to allow the primary hCiPSC colonies to grow larger. In   stage III, it is normal that there will be a large amount of cell death.

對(duì)于第三階段誘導(dǎo), 前 4 天在誘導(dǎo)培養(yǎng)基中加入 VPA (1000 μM)、反苯環(huán)丙胺(10 μM)、DZNep (0.2 μM)和 EPZ5676 (2 μM)。隨后, 在接下來(lái)的 4 天內(nèi)加入 VPA (500 μM), 同時(shí)去除反式環(huán)丙胺、DZNep 和 EPZ5676。不含 VPA、反式環(huán)丙胺、DZNep 或 EPZ5676 的第三階段誘導(dǎo)培養(yǎng)基可以再施用 2-4 天, 以使原代 hCiPSC 集落更大（這一階段出現(xiàn)大量細(xì)胞死亡是正常的）。

6.   Immunofluorescent staining of OCT4 at the end of stage III is recommended and   the OCT4-positive colonies were regarded as primary hCiPSC colonies. Please   leave at least one well of living cells for establishment of hCiPS cell   lines.

建議在第三階段結(jié)束時(shí)對(duì) OCT4 進(jìn)行免疫熒光染色, 并將 OCT4 陽(yáng)性集落視為原代 hCiPSC 集落。請(qǐng)至少保留一個(gè)活細(xì)胞孔以建立 hCiPS 細(xì)胞系。

1.   Preparation plates coated with Laminin-521. Briefly, thaw the Laminin-521 at   2-8℃ before use. Dilute it in PBS to a final concentration   of 5-10 μg/mL. Gently mix and immediately add 0.5mL diluted Laminin-521 to   12-well plate. Incubate at 2-8 ℃ overnight.

涂有層粘連蛋白-521 的制備板。

簡(jiǎn)而言之, 使用前在 2-8℃下解凍層粘連蛋白-521。在 PBS 中將其稀釋至終濃度為 5-10 μg/mL。輕輕混合并立即將 0.5 mL 稀釋的層粘連蛋白-521 添加到 12 孔板中。2-8 ℃下孵育過(guò)夜。

2.   Preparation medium for derivation hCiPS cell lines.

用于衍生 hCiPS 細(xì)胞系的制備培養(yǎng)基。

3.   After 8-12 days stage III condition treatment, cells were dissociated by   Accutase (Millipore) and replated at a ratio from 1:3 to 1:12 on Laminin-521   (STEMCELL) coated plates in the medium for derivation hCiPS cell lines:   Knockout DMEM supplemented with 2% B27 supplement, 1% GlutaMAX, 1% NEAA, 1%   Penicillin-Streptomycin, 50 μg/ml Vc2p, 2 mg/mL AlbuMAXTM-II (AlbuMAXTM-II   could be replaced by 4% KSR) and the small molecules CHIR99021 (1 μM),   PD0325901 (0.5 μM), Y-27632 (10 μM), HRG (20 ng/mL), and bFGF (100 ng/mL).   Cells were incubated under 21% O2, 5% CO2 at 37℃ and the medium was   changed every day.

第三階段條件處理 8-12 天后, 用 Accutase解離細(xì)胞, 并以 1：3 至 1：12 的比例重新接種在層粘連蛋白-521包被的平板上, 用于衍生 hCiPS 細(xì)胞系：補(bǔ)充有 2% B27 補(bǔ)充劑、1% GlutaMAX、1% NEAA、1% 青霉素-鏈霉素、50 μg/mL Vc2p、2 mg/mL AlbuMAXTM-II (AlbuMAXTM-II 可被 4% KSR 替代)和小分子 CHIR99021 (1 μM)的敲除 DMEM,  PD0325901 (0.5 μM)、Y-27632 (10 μM)、HRG (20 ng/mL)和 bFGF (100 ng/mL)。將細(xì)胞在 21% O2、5% CO2 和 37℃下孵育, 每天更換培養(yǎng)基。

4.   After 7-12 days, single compact hCiPSC colony was mechanically picked and   dissociated into small clamps and transferred onto Matrigel coated plates in   mTeSR Plus Medium supplemented with Y-27632 (10 μM).

7-12 天后, 將單個(gè)緊湊的 hCiPSC 集落機(jī)械挑取并解離成小夾具, 并轉(zhuǎn)移到補(bǔ)充有 Y-27632 (10 μM)的 mTeSR Plus 培養(yǎng)基中的基質(zhì)膠包被板上。

5.   After 24 hours, the culture was replaced by fresh mTeSR Plus Medium without   Y-27632.

24 小時(shí)后, 用不含 Y-27632 的新鮮 mTeSR Plus 培養(yǎng)基替換培養(yǎng)物。

hCiPS   cell lines were maintained in mTeSR Plus Medium on Matrigel coated plates   under 21% O2, 5% CO2 at 37 oC. The medium was changed every day. Cells were   passaged when they reach ~85% confluence. This typically occurred at day 3–7   after passaging with split ratios of around 1:10 to 1:20. For passaging,   hCiPS cell lines were dissociated by ReLeSRTM (STEMCELL), and the detached   cell aggregates were transferred onto Matrigel-coated plates in mTeSR Plus   Medium supplemented with Y-27632 (10 μM). Allow the colonies to attach to the   culture plate for 24 hours before replacing the spent medium with fresh mTeSR   Plus Medium without Y-27632.

將 hCiPS 細(xì)胞系維持在 mTeSR Plus 培養(yǎng)基中, 在 21% O2、5% CO2 和 37℃下基質(zhì)膠包被板中。介質(zhì)每天都在更換。當(dāng)細(xì)胞達(dá)到約85%融合度度時(shí)傳代。這通常發(fā)生在傳代后的第 3-7 天, 分流比約為1/10至1/20。對(duì)于傳代, 通過(guò) ReLeSR解離 hCiPS 細(xì)胞系, 并將分離的細(xì)胞聚集體轉(zhuǎn)移到補(bǔ)充有 Y-27632 (10 μM)的 mTeSR Plus 培養(yǎng)基中的基質(zhì)膠包被板上。讓菌落附著在培養(yǎng)板上 24 小時(shí), 然后用不含 Y-27632 的新鮮 mTeSR Plus 培養(yǎng)基替換用過(guò)的培養(yǎng)基。
