Cellules musculaires lisses urothéliales humaines (HUSMC)

01Description

02Informations générales

Description

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.

05Caractéristiques

Morphologie

Spindle-shaped (smooth muscle)

Type de cellule

Primary smooth muscle cells

Tumorigène

No

Temps de doublement

approx. 18 to 36 hours (lot-specific; AcceGen equivalent: ~13 population doublings guaranteed)

06Manipulation et culture

Milieu de culture

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

Atmosphère d'incubation

37°C, 5% CO₂, saturated humidity.

Compléments alimentaires

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.

Réactif de dissociation

Subculture reagents as recommended on the certificate of analysis

Repiquage

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.

Rapport de fractionnement

1 to 3

Densité de semis

More than 4,000 cells/cm²

Renouvellement des fluides

24 hours after seeding, then every 48 to 72 hours

Récupération après le dégel

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

Décongélation et mise en culture

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.

07Contrôle qualité et cryoconservation

Stérilité

Mycoplasma contamination is excluded by PCR.

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

Milieu de congélation

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

Conditions de stockage

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.

Conditions de livraison

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

10Aspects juridiques et sécurité

Consignes de sécurité

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.
