01General information

Description

KMS-12-BM 細胞系是一種從非分泌型多發性骨髓瘤患者的骨髓中建立的人類骨髓瘤細胞系。 該細胞系代表 B 細胞分化的未成熟漿細胞樣階段,其特徵為表達表面標記物 CD20、CD38 及 PCA-1,但不產生免疫球蛋白。這些細胞以其變形的外觀著稱,其中許多呈現多核及巨細胞的特徵。 在超微結構方面,KMS-12-BM 細胞具有發達的粗面內質網,以及具周邊染色質分布的橢圓形偏心細胞核,這正是漿細胞樣細胞的典型特徵。

KMS-12-BM 細胞呈現染色體異常,特別是常與多發性骨髓瘤相關的互補轉位 t(11;14)(q13;q32)。 這些細胞的染色體數目範圍廣泛,從低二倍體到多倍體不等,顯示出顯著的基因組不穩定性。 與其對應的 KMS-12-PE 不同,KMS-12-BM 細胞系不產生澱粉酶,且缺乏免疫球蛋白的分泌或表面表達,因此適合用於涉及非免疫球蛋白產生型骨髓瘤的研究。 此外,該細胞株在軟瓊脂培養條件下克隆效率較低,集落形成率低於 0.1%,且注射至裸鼠體內時不具致瘤性。

06Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Subculturing
透過定期添加或更換培養基來維持培養。以 5 × 10⁵ 細胞/毫升的密度啟動培養,並將細胞濃度維持在 3 × 10⁵ 至 1 × 10⁶ 細胞/毫升的範圍內,以達到最佳生長效果。
Seeding density
5 × 105 個細胞/毫升
Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
