This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,697.

Summary of the Inventive Concept

The present inventive concept relates to improved systems and methods for obtaining 3-dimensional lung-like epithelium, enhancing efficiency, scalability, and safety of lung tissue production for research, therapeutic, and transplantation applications.

Background and Problem Solved

The original patent disclosed methods and systems for growing 3-dimensional lung-like epithelium, but had limitations in terms of culturing conditions, growth factor optimization, and scalability. The present inventive concept addresses these limitations by introducing controlled bioreactors, optimized growth factor cocktails, and large-scale production capabilities, thereby improving the efficiency, quality, and safety of lung tissue production.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system for obtaining 3-dimensional lung-like epithelium, featuring a bioreactor configured to culture cells from NKX2.1+ ventral-anterior foregut spheroid tissue derived from pluripotent stem cells, with controlled oxygen levels and temperature. Additionally, the inventive concept includes methods for enhancing efficiency, scaling up production, and real-time monitoring of 3-dimensional lung-like epithelium formation. These methods involve culturing cells in optimized growth factor cocktails, large-scale bioreactors, and microfluidic devices integrated with sensors and imaging systems.

Novelty and Inventive Step

The new inventive concept introduces novel and non-obvious improvements over the original patent, including the use of controlled bioreactors, optimized growth factor cocktails, and large-scale production capabilities, which significantly enhance the efficiency, quality, and safety of lung tissue production.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include the use of different types of bioreactors, growth factor cocktails, or microfluidic devices. Variations may also include the integration of additional sensors or imaging systems to monitor 3-dimensional lung-like epithelium formation.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the fields of regenerative medicine, tissue engineering, and biomedical research, with potential applications in lung disease modeling, drug discovery, and transplantation therapy.
