Human Tracheal Smooth Muscle Cells (HTSMC)
Primary Human Tracheal Smooth Muscle Cells isolated from the trachea from single donors.
Primary Human Tracheal Smooth Muscle Cells (HTSMC) are isolated from the trachea from single donors and stain positive for smooth muscle α-actin. They connect the endings of the tracheal cartilage by a contractile bridge called the paries membranaceus and consequently regulate the airway lumen. Under pathological conditions like asthma, the amount of smooth muscle cells in the trachea walls is increased leading to smooth muscle hypertrophy or hyperplasia. Hence, HTSMC are suitable for in vitro studies of asthma and other pulmonary diseases.
- Request our GMP grade cell culture media for smooth muscle cells.
- Our HTSMC are now also available from HLA-typed donors.
Recommended plating density | 5000 - 10000 cells per cm2 |
Passage after thawing | P2 |
Tested markers | Smooth muscle α-Actin positive, CD31 negative |
Guaranteed population doubling | > 15 |
Short protocol:
- Trypsinize the cells as usual
- Centrifuge and resuspend in suitable cold freezing medium at a density of 1-4 x 106 cells/ml
- Cool down the cells slowly to -80°C (approx. -1°C per min). We recommend to use "Mr. Frosty" from Nalge or "CoolCell" from Biocision; which both provide gradual and controlled cooling rates when placed in a -80°C freezer overnight.
- Transfer the vials into liquid nitrogen for long-term storage
- Mesenchymal Stem Cells (C-12974/C-12971/C-12977) need Fibronectin-coating when grown in PromoCell MSC Growth Medium XF (C-28019) and when differentiated in MSC Neurogenic (C-28015); Adipogenic (C-28016); or Osteogenic (C-28013) Differentiation Media.
- Human monocyte-derived macrophages (C-12914/C-12916/C-12915/C-12917) must be seeded into Fibronectin-coated culture vessels in combination with PromoCell's M1- and M2-Generation Media XF (C-28055; C-28056).
- For efficient induction of osteoblast mineralization with PromoCell's Osteoblast Mineralization Medium (C-27020); the TC plates should be pre-coated with collagen type I.
- Liquid phase storage provides a consistent temperature of -196°C; a longer holding time and a greater vial capacity but involves the risk of contamination issues.
- Storage in the gas phase is very safe with respect to contaminations but the holding time of the cells is shorter and the vial capacity is reduced.
