Are we oversimplifying wound care?

The industry is starting to challenge long-standing rules like the “30–30 rule” and it’s opening a bigger conversation around variability, performance, and real-world conditions.

Wound healing is often viewed as a clinical challenge.

It is a highly complex biological process driven by cellular interactions, signalling pathways, and the extracellular matrix.

As research evolves, so does our understanding of the role materials play in this process. The shift is clear. Materials are no longer passive. They are designed to actively support the healing environment.

This is where biomaterials and fibre based technologies are beginning to redefine what effective wound care looks like.

At SFM, this aligns closely with how we approach the development of advanced fibre technologies.

How do you see biomaterials shaping the next generation of wound care solutions?

Wound care is evolving rapidly, with growing focus on bioactive materials like hydrogels designed to actively support healing. But while innovation moves forward, the fundamentals remain the same: moisture balance, exudate management, and infection control are still key.

At SFM, we design and manufacture alginate and cellulose-based dressings built on these proven principles - supporting our partners with reliable, high performance solutions.

Innovation builds on strong foundations.

Today, we celebrate an incredible milestone for a truly valued member of the SFM team, Phill Baker.

After an incredible 49 years with the business, Phill retires having played a significant role in shaping SFM into what it is today. Since joining in 1976, he has been a constant through decades of growth, change, and progress, demonstrating remarkable dedication, loyalty, and professionalism throughout his career.

To recognise his outstanding contribution, we are proud to name our pilot plant “The Phill Baker Pilot Plant” a lasting tribute to the impact he has made and the legacy he leaves behind. Phill has been more than a colleague; he has been part of the fabric of SFM, and his presence will be greatly missed by everyone who has had the pleasure of working with him.

We thank Phill for his years of commitment and wish him a long, happy, and well-deserved retirement.

On 25th April, one of our colleagues will be taking on an incredible personal challenge, skydiving in support of the Lily Mae Foundation.

Lily Mae Foundation provides essential support to families affected by baby loss, offering counselling, peer support groups, resources for siblings and fathers, and specialist training for healthcare professionals. Their work ensures that families receive compassionate care and are never left to navigate bereavement alone.

We’re proud to support this challenge and the meaningful cause behind it.

If you would like to contribute, you can do so here:

Angiogenesis Stage 5: Vessel Maturation & Stabilisation

New vessels are not enough.

They must become stable, perfused, and regulated.

In the final phase of angiogenesis:

• Pericytes attach to endothelial cells
• Basement membrane is reformed
• Blood flow becomes established
• Excess vessels regress
• VEGF signalling reduces

This is where temporary vascular networks become functional tissue.

Without maturation, vessels remain fragile and leaky — contributing to chronic inflammation and poor tissue quality.

Angiogenesis is not just about growth.
It’s about controlled resolution.

Smart Wound Dressings That Detect & Respond to Infection

A newly published study in the Royal Society of Chemistry explores a pH-responsive anthocyanin-based hydrogel designed to both monitor infection and deliver targeted antibacterial treatment in real time.

How it works:
Infected wounds typically shift toward an alkaline pH. This hydrogel leverages that change:

• Anthocyanins act as a colourimetric pH indicator, visibly changing colour as pH rises
• Chlorhexidine is incorporated as the antibacterial agent
• When the wound becomes alkaline:
– The dressing changes colour → visual infection monitoring
– Controlled chlorhexidine release is triggered → responsive antimicrobial therapy

A true dual-function system: sensing + treatment.

Key findings:
✔ Strong antibacterial activity against common wound pathogens
✔ Increased drug release under infection-mimicking (alkaline) conditions
✔ Good cytocompatibility with mammalian cells
✔ In vivo (mouse model):
– Reduced bacterial load
– Accelerated wound healing
– Clear visual differentiation between healthy and infected wounds

Why this matters:
This approach supports:
• Earlier infection detection
• More precise antimicrobial use
• Reduced unnecessary exposure
• Alignment with antimicrobial stewardship principles

We are clearly moving toward smart, environment-responsive biomaterials in wound care — integrating diagnostics directly into therapeutic platforms.

Cats aren’t just adorable companions — their purr may offer real benefits for human wellbeing.

Research shows that the frequencies at which cats purr (typically 25–50 Hz) overlap with ranges used in therapeutic vibration and sound therapies — and this has measurable effects on human health.

🧠 Stress & Emotional Wellbeing
• Listening to or petting a purring cat can activate the parasympathetic nervous system — slowing heart rate and lowering blood pressure. This helps reduce stress and anxiety, and promotes relaxation.
• Interactions with cats stimulate the release of oxytocin, often called the “love hormone,” which supports emotional bonding and overall wellbeing.

❤️ Heart & Cardiovascular Health
• Studies have found that cat owners tend to have lower blood pressure and a reduced risk of cardiovascular disease compared to non-owners, potentially linked to reduced stress levels.

💆‍♂️ Calming Frequencies & Potential Physical Effects
• The purr’s frequency range (25–50 Hz) is aligned with frequencies that may promote tissue relaxation and reduce pain perception — similar to therapeutic vibration treatments.
• While direct healing effects (e.g., bone regeneration) in humans require more research, the calming vibrations contribute to a physical sense of comfort and mental ease.

Bottom line: Whether through lowering stress hormones, supporting cardiovascular health, or simply offering calm and comfort, a purring cat brings more to our lives than companionship alone.

Angiogenesis Stage 4: Vascular Network Formation

A single sprout is not enough.

As endothelial stalk cells proliferate, multiple sprouts extend and begin to connect — a process known as anastomosis.

These interconnections create primitive capillary loops within the developing granulation tissue.

At this stage:

• Branching increases
• Vessels fuse and form loops
• Early perfusion begins to restore oxygen delivery
• Fibroblast activity and ECM deposition accelerate

This is the transition from growth to functional infrastructure.

If network formation fails, healing remains incomplete.

Angiogenesis is not just about new vessels — it’s about connected vessels.

02/03/2026

Angiogenesis Stage 3: Capillary Sprouting

Once endothelial cells are activated, structural change begins.

A specialised “tip cell” emerges and extends filopodia toward the VEGF gradient.
Behind it, “stalk cells” proliferate, elongating the developing sprout.

This is not random growth.
It is directional migration driven by molecular signalling.

At this stage:

• Endothelial cells migrate into the wound bed
• The capillary sprout extends toward hypoxic tissue
• Early vascular architecture begins forming

If sprouting is insufficient or misdirected, angiogenesis stalls.

This is the moment vascular regeneration becomes visible.

26/02/2026

Angiogenesis Stage 2: Endothelial Activation

Hypoxia initiates the signal.
Now the vasculature responds.

Once VEGF is released, it binds to VEGF receptors (VEGFR) on nearby endothelial cells.

This binding triggers intracellular signalling cascades that cause endothelial cells to:

• Increase permeability
• Degrade the basement membrane (via MMP activity)
• Transition from a quiescent to migratory phenotype

This is the biological pivot point.

Without endothelial activation, angiogenesis cannot progress to sprouting or vessel formation.

In chronic wounds, this response is often blunted — limiting vascular regeneration at its earliest structural phase.
