Solution Overview

Problem

Somatic cells, particularly in aged or diseased individuals, lose their regenerative capacity and viability, making it challenging to effectively regenerate tissues and repair damaged cells.

Innovation Solution

The use of heparin binding proteins isolated from the medium conditioned by human embryonic stem cells to enhance the proliferation and viability of somatic cells, including muscle and neural cells, by contacting them with the protein composition for a sufficient period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If somatic cells are cultured in vitro, then they can be expanded and studied, but they lose stem cell function and proliferative capacity

Engineering Contradiction:
Improvecell proliferationVSAvoidstem cell function
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent uses conditioned medium from embryonic stem cells as an intermediary substance to transfer regenerative factors to somatic cells. This mediator enables somatic cells to regain proliferative capacity and stem cell function without direct contact with embryonic stem cells, resolving the contradiction between expansion and function preservation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the chemical parameters of the culture medium by supplementing it with specific factors from embryonic stem cell conditioned medium. This parameter change transforms the medium from a standard formulation to one that supports both somatic cell proliferation and stem cell function maintenance.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If somatic cells are taken from aged or diseased individuals, then they can be used for therapy, but they have reduced regenerative capacity and viability

Engineering Contradiction:
Improvetherapeutic applicabilityVSAvoidregenerative capacity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-treating somatic cells with conditioned medium before therapeutic use. This pre-conditioning restores regenerative capacity and viability to cells from aged or diseased individuals, enabling them to function effectively when transplanted back into the patient.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables somatic cells to self-renew and restore their own functionality through exposure to conditioned medium containing stem cell factors. The cells essentially self-service their regenerative capacity without requiring external stem cell transplantation.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If explanted adult stem cells are cultured, then they can be expanded, but they suffer high mortality when reintroduced in vivo

Engineering Contradiction:
Improvecell expansionVSAvoidcell viability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The conditioned medium acts as a protective intermediary that prepares exp lanted stem cells for in vivo reintroduction. It contains factors that enhance cell survival and reduce mortality during the transition from in vitro culture back to the living organism.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Methods and compositions for somatic cell proliferation as well as increasing viability of somatic cells are provided. The compositions include heparin binding protein isolated from a medium conditioned by growth of pluripotent stem cells, such as, human embryonic stem cells, human embryonic carcinoma cells. The methods include contacting a somatic cell with a heparin binding protein composition for a sufficient period of time to provide for enhanced proliferation and/or viability of the somatic cell as compared to the absence of the heparin binding protein composition.
