Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current applications of exosomes derived from mesenchymal stem cells primarily focus on bone regeneration, wound healing, and anti-aging, with a lack of innovation in using antler stem cell-derived exosomes for improving skin quality and promoting hair growth.
Innovation Solution
A method is developed to prepare exosomes from antler periosteal mesenchymal stem cells, involving the collection and processing of antler periosteal tissue, isolation and cultivation of mesenchymal stem cells, and the subsequent isolation and concentration of exosomes, which are then applied to enhance skin quality and promote hair growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exosomes are derived from conventional mesenchymal stem cells (bone marrow or umbilical cord), then they exhibit therapeutic effects, but the cell source is difficult to obtain and has limited proliferative capacity
Solution Approach 1:
The patent uses antler stem cells as a substitute (copy) for conventional mesenchymal stem cells. Antler stem cells replicate the therapeutic properties of bone marrow and umbilical cord MSCs while being easier to obtain and culture, thus resolving the contradiction between reliability of therapeutic effect and ease of manufacture
Solution Approach 2:
The patent changes the source parameter of stem cells from conventional difficult-to-obtain sources to antler-derived cells. This parameter change maintains the therapeutic efficacy while dramatically improving ease of obtaining cell source and proliferative capacity
2Reliability
If exosomes are derived from conventional mesenchymal stem cells, then they show therapeutic potential, but the proliferative capacity is limited to about 15 passages
Solution Approach 1:
Antler stem cells serve as a superior copy of conventional MSCs, maintaining all therapeutic properties while achieving 55+ passages of proliferation. This resolves the contradiction between maintaining therapeutic reliability and achieving high productivity through sustained cell proliferation
Solution Approach 2:
The patent changes the biological parameter of proliferative capacity by switching from conventional MSC sources to antler-derived stem cells. This parameter change enables continuous production of exosomes at high levels without the 15-passage limitation of conventional cells
3Reliability
If existing applications focus on bone regeneration and wound healing, then established therapeutic uses are achieved, but innovation in skin quality improvement and hair growth is lacking
Solution Approach 1:
The patent demonstrates that antler stem cell-derived exosomes possess universal therapeutic properties applicable across multiple tissue types and conditions. By showing efficacy in skin quality improvement and hair growth in addition to traditional bone and wound applications, the invention achieves multi-functionality and expands adaptability while maintaining reliable therapeutic effects
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The exosomes derived from antler periosteal mesenchymal stem cells significantly improve skin texture and quality, reduce sebum secretion, and enhance hair growth, demonstrating a substantial increase in moisture content, glossiness, and hair volume, while reducing skin roughness and fine lines.
Implementation Method 1
The chopped periosteal tissue is then mixed with digestive enzymes and incubated in a CO2 incubator for decomposition
Implementation Method 2
filtered through a cell strainer, and centrifuged. The primary periosteal cells are collected from the cell pellet at the bottom of the centrifuge tube
Implementation Method 3
The alpha-MEM culture medium from the seven-day culture is filtered using a 0.22 μm filter
Implementation Method 4
The exosomes are isolated and concentrated using tangential flow filtration (TFF)

AI summary
The present invention provides a method for preparing exosomes derived from antler periosteal mesenchymal stem cells and their applications. After obtaining antler periosteal tissue, the tissue is placed in a DPBS culture dish containing antibiotics for further processing. The periosteal tissue is then minced and washed with DPBS until it is free of blood. The minced tissue is treated with digestive enzymes and incubated in a carbon dioxide (CO2) incubator to facilitate enzymatic digestion. Subsequently, alpha-MEM complete culture medium is added to further process the tissue. The digested tissue is filtered and centrifuged to isolate the primary periosteal cells, which are then counted and cultured in a suitable medium to obtain mesenchymal stem cells (MSCs) derived from antler periosteum. The cultured periosteal MSCs are further processed to isolate exosomes, which can be applied to promote the proliferation and repair of human fibroblasts, enhance skin quality, and stimulate hair growth.
