Technologies of Stem Cell Therapy

Stem Cell Therapy Ltd. has developed a suite of technological platforms centred on advanced cell engineering for therapeutic purposes. The company’s technology can be broadly categorised into two main areas.

  • 3D Cell Culture Technology: This involves cultivating cells in a 3D environment, which better simulates the conditions within the human body compared to traditional two-dimensional (2D) culture systems. This method is crucial for producing cells that are more physiologically relevant and, therefore, potentially more effective in treating various conditions.
  • Hydrogel-Based Cell Cultivation: Hydrogels are used as a scaffold within which cells can grow and develop in three dimensions. This mimics the extracellular matrix found in the body, providing structural support and enabling cells to maintain their shape and function.

The combination of these technologies allows Stem Cell Therapy Ltd. to develop ‘off-the-shelf’ cell therapy products that are ready to use. These products are designed to be easily integrated into existing medical practices and are GMP-compatible, meaning they meet the stringent quality requirements for clinical use. This technology is applied across a range of therapeutic areas, including bone and cartilage regeneration, which addresses significant unmet medical needs.

1. Three-Dimensional (3D) Cell Culture Technology

Stem Cell Therapy Ltd. has adopted 3D Cell Culture Technology as a cornerstone of its research and development activities. This technology represents a significant advancement from the traditional two-dimensional (2D) cell culture, where cells are grown in flat layers on a plate. In contrast, 3D cell culture allows cells to grow in all directions, akin to how they would in a living organism.

The 3D approach provides a more realistic environment for cells to interact, which is essential for understanding how they behave in the human body. This method has become increasingly important in the study of complex biological processes, drug development, and regenerative medicine.

In practice, 3D cell cultures are facilitated by the use of hydrogels, which serve as a scaffold to support the cells. These hydrogels are designed to mimic the natural extracellular matrix, providing the cells with the necessary cues for growth and function. By adjusting the stiffness of the hydrogels, a property known as ‘biomimetic tuning’, Stem Cell Therapy Ltd. can tailor the environment to suit different types of cells, from softer gels for bone or fat tissue cells to stiffer ones for bone or cartilage cells.

Furthermore, the company utilises ‘Designer Gels’, a type of tunable hydrogel, for creating conditions that guide stem cells along specific paths of development. This is crucial for stem cell therapy, where the aim is to produce cells that can replace damaged tissues in diseases or injuries.

2. Hydrogel-Based Cell Cultivation

Hydrogel-based cell cultivation is a sophisticated technique utilised by Stem Cell Therapy Ltd. to support the growth and development of cells in a three-dimensional environment. Hydrogels are water-rich polymers that can simulate the physical properties of a natural extracellular matrix, providing a supportive scaffold for cells. This environment allows cells to maintain their shape, proliferate, and differentiate in a manner more reflective of their natural state within the human body.

In the context of stem cell therapy, where the accurate differentiation of stem cells is crucial, the stiffness (or biomimetic tuning) of the hydrogel can be adjusted to mimic the conditions of different types of body tissues. For instance, softer hydrogels may be used to culture cells that will become bone tissue, while stiffer hydrogels are suitable for bone tissue cells. This precision in controlling the physical milieu of the cells is pivotal for guiding their development into the desired cell types.

Stem Cell Therapy Ltd.’s hydrogel technology is not only biomimetic but also tunable, allowing the manipulation of physical properties to direct stem cell lineage specification. This means that by altering the stiffness of the hydrogel, stem cells can be coaxed into differentiating into specific cell types required for repairing tissues or treating diseases.

The company’s approach includes the use of ‘Designer Gels’, which are hydrogels with finely tuned properties that can be adjusted for optimal cell growth and differentiation. These gels provide the necessary signals that influence cell behaviour, such as promoting bone formation or vascularisation in tissue engineering applications.

Stem Cell Therapy Ltd.’s hydrogel-based cultivation process is meticulously designed to support the 3D culture of cells. This process begins with the preparation of the hydrogel substrate, followed by the seeding of cells onto this substrate. The hydrogel provides a supportive and nutrient-rich environment, much like the natural extracellular matrix, allowing cells to grow and proliferate effectively.

After seeding, the cells are incubated within this hydrogel matrix, where they can expand in a three-dimensional space. This is a critical step, as it allows for the establishment of a robust cell culture that more accurately reflects the natural growth patterns and interactions of cells in living tissues.

The next phase involves the differentiation of these cells, a process which is guided by the change of media to one that is specific to the desired cell type. This media provides the biochemical cues necessary for the cells to differentiate. Differentiation is a highly controlled process that is essential for the production of cells with specific functions, such as bone, cartilage, or nerve cells.

An important aspect of Stem Cell Therapy Ltd.’s process is the use of gas-permeable films within the culture system. This feature ensures that the cells receive adequate levels of oxygen and that carbon dioxide is removed, mimicking the gas exchange that occurs in blood vessels. This gas exchange is essential for maintaining the cells’ metabolic processes and overall health.

Moreover, the company’s approach to hydrogel-based cell cultivation aims to optimise the physical space around the cells. The space must be sufficient to allow for cell expansion and growth but also needs to be regulated to prevent the formation of bubbles that could disrupt the uniformity of the cell culture.

By controlling these environmental parameters, Stem Cell Therapy Ltd. can cultivate cells that not only grow in a more physiologically relevant configuration but also maintain their function after being thawed from frozen states. This is particularly important for the development of off-the-shelf cell therapy products, which require a high degree of viability and efficacy post-thaw to be clinically useful.

The company’s cell cultivation method is demonstrated to be effective in producing cells that show homogeneity in growth and function, which is critical for ensuring the quality and consistency of therapeutic cell batches. This uniformity is vital when scaling up production for commercialisation and clinical application, ensuring that patients receive a reliable and effective cell-based therapy.

3. Evaluating Immunogenicity in Cell Therapy Development

When developing cell therapies, a critical factor to consider is the immunogenicity of the therapeutic cells. This refers to the potential of these cells to provoke an immune response in the recipient. The goal is to ensure that the cells will be compatible and not rejected by the patient’s immune system. For instance, experiments using a xenogeneic model, where human cells are implanted into non-human hosts, help determine whether the cells can survive without provoking an immune response that would lead to their rejection.

In vitro studies, such as the Mixed Lymphocyte Reaction (MLR), measure the proliferation of lymphocytes when exposed to the MSCs, providing insights into the level of immune response the therapeutic cells may induce. A low level of lymphocyte proliferation suggests that the cells are less likely to be rejected.

Further analysis in syngeneic models, where the donor and recipient are genetically identical, such as inbred rats or mice, provides additional data on the immune compatibility of the cells. This is crucial for autologous therapies, where the patient’s own cells are used for treatment.

In allogeneic therapies, where the cells are derived from a donor different from the recipient, it is essential to ensure that the donor cells do not carry high levels of immunogenic markers. The presence of such markers could lead to an adverse immune response in the recipient.

Ensuring low immunogenicity is a step towards achieving therapies with higher success rates and lower risks of complications related to immune rejection.
