Опис

Primary Human Pulmonary Artery Smooth Muscle Cells (HPASMC) are isolated from the pulmonary artery. They are a key model for pulmonary arterial hypertension, including hypoxia-driven proliferation and vascular remodeling.

Hypoxia drives the proliferation of HPASMC, and PDGF-BB shifts them toward a synthetic, migratory phenotype, reproducing key features of pulmonary vascular remodeling. Because the balance of BMP and TGF-β signaling is central to pulmonary arterial hypertension, the cells are also used to study BMPR2-related mechanisms.

06Обробка та вирощування

Живильне середовище

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

Атмосфера інкубації

37°C, 5% CO₂, saturated humidity.

Добавки

Supplement as specified in the AddexBio SMC supplement kit (refer to specification sheet). For cryopreservation: complete culture medium + 5% (v/v) DMSO.

Реагент для дисоціації

Subculture reagents as recommended on the certificate of analysis

Пересадка в нове середовище

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.

Коефіцієнт розподілу

1 to 3

Щільність висіву

More than 4,000 cells/cm²

Оновлення рідини

24 hours after seeding, then every 48 to 72 hours

Відновлення після відлиги

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

Розморожування та культивування

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.

07Контроль якості та кріоконсервація

Стерильність

Mycoplasma contamination is excluded by PCR.

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

Середовище для заморожування

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

Умови зберігання

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.

Умови доставки

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

10Правові питання та безпека

Заходи безпеки

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.
