“Autoimmune diseases can affect fertility through inflammation, hormonal disruption, and harmful antibodies that interfere with reproductive processes

They may impact egg or sperm quality, contribute to implantation failure, and increase the risk of miscarriage or pregnancy complications. Conditions such as Systemic Lupus Erythematosus, Hashimoto’s Thyroiditis, and Antiphospholipid Syndrome are known to influence reproductive health

Early assessment and appropriate care can help manage these risks and support fertility.

“Controlled Oxygen Delivery: A Missing Piece in Tissue Regeneration

Scientific review highlights a challenge that many regenerative medicine researchers know well .

Thank to: Elizabeth Zoneff, Serena Duchi, Carmine Onofrillo, Brooke Farrugia, Simon Moulton, Clare Parish and other autors

Oxygen is not just supportive. It is decisive.

• Engineered tissues do not initially have their own vascular system.
• Cells inside scaffolds depend on passive oxygen diffusion, which is effective only over very short distances – typically ~100–200 µm.

Beyond that distance:

• oxygen levels drop
• cells experience hypoxia

This is one of the main causes of tissue-engineering graft failure.

The task is simple in theory, but difficult in practice:

• Maintain sufficient and controlled oxygen supply until the host vasculature grows into the implant.
• This period typically lasts about 10–14 days, depending on the tissue type.

However, oxygen delivery must be precisely controlled:

• Too little → hypoxia and cell death
• Too much → ROS formation and oxidative damage

Biology already uses this mechanism.

During embryonic development, controlled oxygen gradients regulate tissue formation, and HIF signaling pathways stimulate angiogenesis through VEGF.

Regeneration therefore depends on carefully regulated oxygen environments.

Two main strategies emerging

Researchers are exploring two major approaches:

1. Oxygen carrier and delivery solution
2. Devices that helps actively delivery and circulate

A point that deserves clarification
The scientific literature often treats HBOCs as a single class, but this is a simplification

Hemoglobin biology is extraordinarily diverse.

Even in humans, thousands of hemoglobin variants exist with different functional characteristics.

And we are not tolkin about production technology and purity

Current research shows that these mechanisms are far more complex than initially interpreted.
Importantly, bovine hemoglobin-based carriers such as Hemopure / Oxyglobin have reached regulatory approval and real clinical use.

These systems demonstrate that controlled oxygen transport is feasible when the biology is properly understood.

One conclusion from the review is clear

For many regenerative systems, the first 10–12 days after implantation are critical, and providing controlled oxygen support during this window may determine success or failure.

Call to the regenerative medicine and Biotech community

Researchers working in:

• tissue engineering
• regeneration
• transplantation
• wound healing

We will provide you new solutions.
