Understanding Tissue Engineering and Biomaterial-Based Regenerative Medicine

Medical sciences have evolved significantly over the past few decades. Conditions that were once hard to detect and diagnose now have treatment options available. But with any other domain, much remains to be explored in the world of medicine. Tissue engineering and regenerative medicine are emerging fields with the potential to transform healthcare as we see it today.

But what exactly is tissue engineering? And what does regenerative medicine mean? Are they both the same or different? Continue reading as we answer these questions and offer insights into the tissue engineering and biomaterial-based regenerative medicine market landscape.

What Is Tissue Engineering?

Tissue engineering is a part of the bioengineering field. Bioengineering is a discipline that applies engineering principles to biomedical technologies and biological systems. Tissue engineering is sometimes described as adopting an engineering approach to studying biology.

Bioengineers work in healthcare on areas such as device design and physical therapy. They also contribute to drug delivery by providing insight into the time it takes for a tablet coating to break down and exert its effect.

Tissue engineering involves the investigation of the physical, biological, and chemical forces that are involved in the development of tissue and healing wounds. The field aims at restoring, improving, or replacing biological tissues. This requires an understanding of what a healthy tissue condition is like. Tissue engineers grow cells in a laboratory for the same. These cells act like the healthy cells grown in the body.

Are Tissue Engineering and Regenerative Medicine the Same?

You’ll often find the terms “tissue engineering” and “regenerative medicine” being used interchangeably. And indeed, both of them focus on repairing and restoring biological tissues. However, they are somewhat different. The main difference lies in the focus area of these fields. Tissue engineering focuses on growing tissues inside a lab. That is outside the body. On the other hand, regenerative medicine uses tissue-engineering techniques in a healthcare setting for tissue repair within the body.

What is the Market Outlook?

What Are the Principles of Tissue Engineering?

Tissue engineering uses life sciences and engineering methods to replace or improve biological tissues. Various tissues of the body can be formed artificially. These include bone, muscle, bladder, and vessels, amongst others. Here are the three key elements that define tissue engineering:

Stem Cells: Stem cells have the capability of differentiating into more than one type of cell. In adults, stem cells can differentiate into several different types of cells. The differentiation of these cells is based on their origin in the body. Several factors affect the path taken by cells in the body. These include mechanical forces and chemical exposure, amongst others.

Scaffolds: These are 3D structures. They support the growth of stem cells into the desired tissue or cell type. The growth of cells in a lab is typically done on flat surfaces. In some cases, the cells may be suspended in a liquid. The material used in the scaffold is biocompatible, meaning it won’t damage the tissues that are in contact with it. Collagen and certain protein chains are typically used as materials in scaffolds.

Bioactive Molecules: These substances act as practical tools for regulating cell processes. They are used in tissue engineering to signal molecules or growth factors that can influence the differentiation of a stem cell. They can be a part of the nutrient mix used for growing cells in a lab. Bioactive molecules can also be a part of the scaffold during the manufacturing stage.

What Are the Steps Involved in Growing New Tissue?

Here’s how new tissue is growing by applying the key factors of tissue engineering:

• The first step involves the isolation of cells during a biopsy. The isolation of cells can be achieved using apheresis or centrifugation. Isolation requires the cells to be in a free-floating stage. For that, the tissue is minced and digested using enzymes. The extraction may be difficult if it’s being done from solid tissues.
• The next step sees the cultivation and further proliferation of the isolated cells. This is done to have a sufficient number of living cells.
• After isolation, the cells are planted into the scaffold. In an ideal environment, the scaffold regulates the adhesion and proliferation of cells. The physical structure of the scaffold controls cell functions by regulating nutrient diffusion and cell-cell interactions. The surface chemistry of the scaffold has an indirect effect on cell adhesion and subsequent molecular activity. This stage may involve the use of bioreactors for maintaining optimal conditions.
• The next step involves the development of the specific tissue. This is achieved through the use of a specific scaffold.
• Once the tissue is grown, it can be implanted in the living body.

How Is AI Transforming the Fields?

Artificial intelligence (AI) has the capability to analyze architectural plans and structural parameters. This helps in the creation of optimized and material-efficient 3D models. The real-time monitoring capabilities of AI ensure the models have high precision and can maintain their quality throughout construction. Furthermore, the predictive maintenance capabilities of AI help improve the operational reliability of 3D construction and reduce maintenance costs.

To Conclude

Tissue engineering serves as an important tool to help researchers understand how certain conditions progress and what treatment options can be used. Regenerative medicine offers a potential alternative to traditional treatments. Therapies based on tissue engineering and biomaterial-based regenerative medicine are already being approved in major regions globally. The tissue engineering and biomaterial-based regenerative medicine market is expected to witness significant growth in the coming years.
