바이오전기 스캐폴드를 이용한 약물 개발 – 3D 프린팅의 또 다른 활용 사례

The additive manufacturing sector continues to show near-limitless potential. Innovations have taken 3D printers from creating customized figurines all the way to printing entire neighborhoods, working electronics, and even human organs. Now, researchers at Washington University in St. Louis have developed a novel method for 3D-printing bioelectronic scaffolds designed to support tissue formation. While this technology does not yet enable the direct printing of fully functional organs, it represents a significant step toward improving engineered tissue for medical applications.

전통적인 조직 개발 방법

Most people are unaware that tissue development is a crucial process of drug testing and other vital medical practices. Researchers will use natural or artificially created scaffolds that support a variety of cells, including primary cells, stem cells, and immortalized cell lines, to create living tissue for drug testing and other purposes.

The scaffolding allows the cells to grow and develop. The goal is to recreate human physiology, allowing for testing and monitoring of treatments on living cells. For example, researchers could use these scaffolds to create tissue models for drug testing, potentially improving our understanding of how medications interact with biological systems.

바이오전자공학

The field of bioelectronics focuses on integrating electronic properties with biological systems. The research from Washington University leverages this concept by developing 3D-printed scaffolds that support tissue formation while maintaining electrical conductivity, which could be useful in drug development and regenerative medicine. These devices provide more flexibility in terms of applications and capabilities.

흥미롭게도, 바이오전자공학은 전자 자극을 사용해 질병을 치료한다는 백년 된 이론에 기반합니다. 고대 이집트와 같은 문화에서는 전기 물고기와 같은 전기 동물을 이용해 통증과 염증을 완화시키곤 했습니다.

1600년대에 전기 치료는 유럽 전역에서 실용적인 의료 관행이었습니다. 1800년대에 인간은 전기를 독립적으로 생성하고 활용하는 방법을 배우게 되었으며, 이는 자연에서 전기를 생산하는 동물을 이용할 필요성을 없앴습니다. 오늘날 바이오전자 기술은 다양한 이유로 널리 사용되고 있습니다.

바이오전자공학의 단점

Today, the bioelectronics market is limited because the majority of conductive material is stiff. This stiffness has reduced its ability to be used in certain scenarios where its physiological restrictions could cause adverse effects. Thankfully, this scenario may be about to change.

바이오전기 스캐폴드 연구

A recent 연구¹가 Advanced Materials Technologies 저널에 “소프트 조직과 유사한 강성을 가진 3D 프린팅 바이오전기 스캐폴드”라는 제목으로 발표되었으며, 신뢰할 수 있는 바이오전기 스캐폴드를 제작할 수 있는 새로운 3D 프린팅 방법을 소개합니다. 연구진에 따르면 이러한 3D 프린팅 바이오전기 스캐폴드는 세포와 조직 성장에 이상적인 환경을 제공합니다.

PEDOT: PSS,

The study delves into the use of a new material called PEDOT: PSS (Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) as the scaffolding structure. Interestingly, it’s built in a lattice-like structure designed to help support the cells. Notably, this scaffolding is immersed in a water-based gel as part of the process.

이 겔은 150~300 마이크로미터 크기의 많은 기공을 가지고 있습니다. 육안으로 볼 때 스캐폴드는 6mm 너비의 어두운 색 점처럼 보이며 별다른 용도가 없어 보입니다. 그러나 이러한 기공은 건강한 세포 성장을 촉진하는 중요한 구성 요소입니다.

The pores help determine key factors like how fast and in what direction the cell culture will develop. It also plays a role in how each cell will interact and multiply. This flexibility enables researchers to fine-tune their creations with exact specifications. They can even adjust little details like pore angle to alter the entire support structure grid line layout.

바이오전기 스캐폴드 테스트 결과

The engineers found that their scaffolding held up excellently compared to traditional methods. They discovered that using PEDOT: PSS provides multiple benefits including stability and conductive capabilities. This trait allows for the creation of hydrated electronic systems

This style of electronics exists within a living framework. They could one day be crucial in the treatment process for serious injuries and more. The key factor is that the framework excelled at maintaining biostability. Additional tests demonstrated the cells demonstrated high morphology and proliferation, making it the ideal microenvironment for growth.

바이오전기 스캐폴드의 장점

There’s a long list of benefits that this study brings to the market.  For one, its flexibility means the technology will allow researchers to create new tissue testing methods and electronics. These innovative trials could lead to major medical breakthroughs.

더 빠르게

The 3D-printing approach allows researchers to precisely design scaffold structures, potentially streamlining aspects of tissue engineering. However, the overall tissue growth process still requires time for cells to develop and integrate within the scaffold. In the past, lab-grown samples could take weeks to complete and mature. Additionally, they are time-consuming to gather or create on an individual basis. This new 3D printing method improves efficiency, eliminates waste, and provides much faster print times.

유연성

One of the main benefits of this research is its flexibility. The team noted that they could alter many aspects of the cell’s development simply by changing the size and location of the scaffolding to each other. This flexibility will allow engineers to create the exact type of tissue needed to ensure their latest treatments remain effective.

접근성

Another major benefit of this research is the fact that 3D-printed tissue is far more accessible than traditionally lab-grown samples. Enabling drug manufacturers to easily print tissue will result in faster and more thorough drug inspections. In the future, this style of 3D printer may be found in your local healthcare facility where it could serve several roles in your treatment process.

바이오전기 스캐폴드 적용 분야

There’s a long list of potential applications for this technology. You could see a day when these structures are used to support human tissue repair or implants. It’s ideal for this scenario because it can be created quickly, customized to patients’ requirements, and can support direct electronic and sensor integrations.

임플란트, 심박조율기 및 기타 스마트 기술을 3D 프린팅할 수 있는 능력은 시장을 확실히 변화시킬 것입니다. 앞으로 이 기술은 더 가볍고 빠르며 강한 장치를 만들게 되며, 이는 더 내구성이 높고 피부 조직을 모방합니다. 이러한 장치는 센서가 탑재되어 건강의 모든 측면에 대한 귀중한 통찰을 제공할 것입니다.

Additionally, this research will lead to more in-depth studies around cellular activity, unlocking new biophysical links that engineers never suspected. As such, engineers can use this tech to ensure that new drugs receive the highest level of testing before approval, lowering the risk of malpractice and injury.
