Exosomes are small extracellular vesicles (30-150 nm) that play a crucial role in cell-to-cell communication by transferring proteins, lipids, and nucleic acids between cells. Macrophage-derived exosomes (MDEs) have garnered significant attention in recent years for their role in tumorigenesis, the process by which normal cells transform into cancer cells. Macrophage-Derived Exosomes have key roles in tumorigenesis

Freeze drying, also known as lyophilization, is a dehydration process typically used to preserve structural integrity and the qualities of perishable materials and biological samples. This technique has found significant applications in various fields, including research and medicine. Here, we explore the principles of freeze drying, its applications, and its impact on research and medical practices.

Low-level chronic inflammation is a hallmark of ageing. A recent article in Nature suggests the goals of longevity research to increase healthspan, as well as lifespan, may be achieved by simply inhibiting an inflammatory cytokine.

The RGD peptide is the most widely used in cell culture. RGD is a natural motif that binds to common cell receptors providing binding points to substrates. The origins and the myriad of applications of RGD are discussed.

Collagen can fail to gelate. This may be due to a multiple of factors which are discussed in this article.

Cancer is the second leading cause of death worldwide, after cardiovascular disease, with over 16.4 million cancer-related deaths predicted by 2040. It is well known for its complex and dynamic nature, which has meant that it is challenging to study with 2D cell culture models, although understanding of the disease has improved.

We're attending ISSCR in Hamburg from 10-12 July Come and say hello and find out about our products and services. We're going to be featuring PODS, the 100% protein slow-release growth factors

In autologous cell therapy, cells that originate in the patient are returned to the patient for therapeutic purposes. If we accept the obvious notion that human cells grow best in humans, the quicker cells can be re-implanted, the better. But many cells require complex, sustained manipulation to differentiate and mature into the cells required for therapeutic effect. Technologies that enable cells to differentiate and maturate autonomously in the patient following implant will enable this goal.

It is important to understand that there is a big difference between in vivo and in vitro stability of growth factors. In-vivo, growth factor half-lives can be just a few minutes. But the same growth factors have in-vitro half-lives of a few hours. What causes this?

In an exciting development, biomaterials scientists have used advanced biomaterials and an ingenious manufacturing method to produce co-axial extruded, cellularized blood vessels incorporating cells derived in situ from fat stem cells from the patient.
