Lung Biotechnology PBC Cell Scaffold Patent Application US20260109952A1
Summary
Lung Biotechnology PBC has filed US Patent Application US20260109952A1, published April 23, 2026, for a printable composition used to manufacture cell-receiving scaffolds. The composition comprises approximately 0.3 to 3.0 wt% collagen, 5.0 to 40.0 wt% monomers, 0.5 to 2.0 wt% photoinitiator, and up to 75 wt% protic solvent vehicle. The application claims a printing resolution of 100 microns or less, specific photo speed parameters (Dp/Ec of 0.1-5 mm Dp and 10-100 mJ/cm² Ec), and a green strength of at least 5 kPa after drying. The patent also covers methods for manufacturing three-dimensional cell-receiving scaffolds using the composition. Inventors include Pingyong Xu, Luis Alvarez, Derek Morris, and Iman Yazdi, with filing date December 10, 2025.

Abstract
A printable composition for the manufacture of cell-receiving scaffolds comprising about 0.3 wt % to about 3.0 wt % of one or more collagens; about 5.0 wt % to about 40.0 wt % of one or more monomers; about 0.5 wt % to about 2.0 wt % of a photo initiator; and 0 wt % to about 75 wt % of a vehicle comprising a protic solvent, by weight of the printable composition; wherein the printable composition has a resolution of about 100 microns or less when printed, a photo speed (Dp/Ec) of about 0.1-5 mm (Dp) and about 10-100 mJ/cm2 (Ec) when printed, and a green strength of at least about 5 kPa after drying. The present technology further includes methods of manufacturing a three-dimensional cell-receiving scaffold using the printable composition.
