Description

Cell Line Origin

Human Caucasian foetal lung

Cell Line Description

From normal embryonic lung of female. Have very broad human virus spectra, especially useful for isolation of rhinoviruses. Cells form multilayered membrane when held for long periods at 37°C with periodic pH adjustments. Used in preparation of human virus vaccines.

Application

From normal female embryonic lung (expect collagen production). These cells have a very broad human virus spectra. Particularly useful for the isolation of rhinovirus. Cells from multilatered membrane when incubated for long periods with periodic pH adjustments. Used in the preparation of human virus vaccines.

Subculture: Spit at 70-80% confluency, approx. 1:3 to 1:6, seed at 2-4x10⁴ viable cells/cm². Trypsinize using 0.25% solution, with or without EDTA, 37 °C and 5% CO₂.

Virus studies (rhinoviruses), vaccine production

WI 38 human cell line has also been used to study the cytotoxicity of acrylic based resin compounds and silica nanoparticles.

Biochem/physiol Actions
