| Growth Conditions |
Culture medium: For adherent cultures: DMEM:Ham's F12 (1:1) ,w: 3.1 g/L Glucose ,w: 2.5 mM L-Glutamine ,w: 15 mM HEPES ,w: 0.5 mM Sodium pyruvate ,w: 1.2 g/L NaHCO3 (Cytion article number 820400a)For suspension cultures: CHO Growth Medium A (from InSCREENeX; InSCREENeX catalog number INS-ME-1039). Supplements: For adherent cultures: Supplement the medium with 5% FBS. Add Geneticin (G418-Sulfat) to achieve a final concentration of 0.5 mg/mL. Dissociation reagent: For adherent cultures: Trypsin-EDTA. Seeding density: 2 to 5 x 10⁴ cells/cm². Freeze medium: As a cryopreservation medium ,we use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability ,or CM-1 (Cytion catalog number 800100) ,which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. Incubation atmosphere: 37°C ,5% CO2 ,humidified atmosphere. |

The CHO-CXCR7-Medium-high cell line is a stable recombinant CHO (Chinese Hamster Ovary) cell line engineered to express the CXCR7 receptor at a medium-high level. This cell line was created using an innovative landing pad technology, which allows for targeted integration of the CXCR7 gene at a pre-validated genomic locus, ensuring consistent and reproducible expression. CXCR7, also known as ACKR3, is an atypical chemokine receptor involved in immune modulation and cancer biology. Unlike typical GPCRs, CXCR7 does not signal through G proteins but instead scavenges chemokines such as CXCL12 and CXCL11, and forms heterodimers with CXCR4, influencing processes like tumor progression, metastasis, and angiogenesis.
CXCR7 is notably overexpressed in various cancers, including breast, lung, and prostate cancers, where it is linked to increased tumor growth, metastasis, and poorer prognosis. This makes the CHO-CXCR7-Medium-high cell line particularly valuable for oncology research, allowing for the study of CXCR7’s role in cancer progression and its potential as a therapeutic target. The expression of CXCR7 in this cell line was confirmed using flow cytometry.
Společnost Cytion vznikla v roce 2004 v německém Heidelbergu s jasným vědeckým posláním: dodávat ověřené lidské a zvířecí buněčné linie bez kontaminace, připravené za přísně kontrolovaných laboratorních podmínek.
Postupně se vypracovala ve spolehlivou buněčnou banku, která slouží akademickým laboratořím, biotechnologickým firmám i farmaceutickým výzkumným týmům po celém světě. Klade přitom důraz na reprodukovatelnost výsledků, přísnou kontrolu kvality a dlouhodobá partnerství.
