Açıklama

Primary Human Bladder Smooth Muscle Cells (HBdSMC) are isolated from the smooth muscle layer of the urinary tract. They are used to study the response of the bladder wall to mechanical stretch and as a building block for engineered bladder tissue.

HBdSMC respond to cyclic stretch and hydrostatic pressure that mimic bladder filling with increased proliferation and altered contractility, involving muscarinic receptor signaling. This makes them a model for detrusor remodeling in bladder outlet obstruction and for conditioning cells in bladder tissue engineering.

06İşleme ve yetiştirme

Besiyeri

Smooth Muscle Cell Growth Medium kit (Cytion article number 850075); Smooth Muscle Cell Growth Medium mix (Cytion article number 850074)

Kuluçka ortamı

37°C, 5% CO₂, saturated humidity.

Takviyeler

Supplement per AcceGen medium kit instructions. Standard SMC growth medium contains FBS (5–10%), EGF, FGF, and insulin as major components. Refer to product-specific CoA.

Ayrıştırma reaktifi

Subculture reagents as recommended on the certificate of analysis

Alt kültür oluşturma

Subculture the cells at about 75 % confluence. Denser cultures undergo irreversible contact inhibition and stop proliferating. Use the subculture reagents recommended on the certificate of analysis.

Bölünme oranı

1 to 3

Ekim yoğunluğu

More than 4,000 cells/cm²

Sıvı değişimi

24 hours after seeding, then every 48 to 72 hours

Çözülme sonrası toparlanma

Post-thaw viability ≥ 70 % viable cells. More than 80 % confluence within the expected recovery period.

Çözme ve kültürleme

1. Thaw the cryovial quickly in a 37 °C water bath, swirling gently. Just before the last ice has melted, move the vial to a laminar flow hood and decontaminate its outer surface.

2. Transfer the cell suspension into a 15 ml centrifuge tube, add 10 ml of Smooth Muscle Cell Growth Medium and centrifuge at 250 × g for 5 minutes.

3. Remove the supernatant and resuspend the cell pellet in 10 ml of Smooth Muscle Cell Growth Medium. Check cell number and viability.

4. Divide the suspension between two 25 cm² culture flasks (5 ml each). Using two flasks reduces the risk of losing all cells if a passage fails.

5. Incubate at 37 °C, 5 % CO₂ and saturated humidity, with the screw caps opened by half a turn for gas exchange.

6. Change the medium after 24 hours to remove unattached cells, then every 48 to 72 hours, using pre-warmed medium only.

7. Subculture the cells at about 75 % confluence. Denser cultures undergo irreversible contact inhibition and stop proliferating. Use the subculture reagents recommended on the certificate of analysis.

8. Recommended seeding density: more than 4,000 cells/cm².

07Kalite kontrol ve kriyoprezervasyon

Kısırlık

Mycoplasma contamination is excluded by PCR.

To ensure there is no bacterial, fungal or yeast contamination, cultures are subjected to visual inspection.

Dondurma ortamı

As a cryopreservation medium, we use complete growth medium + 10% DMSO for adequate post-thaw viability.

Saklama koşulları

For long-term preservation, store vials in liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable for up to one week only.

Nakliye koşulları

Cryopreserved primary cells are shipped on dry ice. On receipt, check the cryovial for damage and transfer it without delay to appropriate storage.

10Yasal ve güvenlik

Güvenlik önlemleri

When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments. Primary cells are of human origin, and no known test procedure can ensure the complete absence of infectious agents. Handle all products as potentially infectious.
