Biologics

Amniotic and birth tissue biologics are naturally rich in growth factors, cytokines, and proteins that support the body's healing process — helping to reduce inflammation and promote tissue repair in damaged joints without surgery.

Growth Factors in Biologics:
How They Support Healing

Growth factors are signaling proteins present in amniotic and birth tissue preparations. They help coordinate the biological environment of a healing joint — influencing inflammation, cellular activity, and tissue remodeling.

How Growth Factors Signal Repair

Growth factors bind to specific receptors on target cells, triggering intracellular signaling cascades that activate genes responsible for proliferation, differentiation, and extracellular matrix production.

Cartilage & Tendon Regeneration

Key growth factors like TGF-β, IGF-1, and FGF directly stimulate chondrocytes (cartilage cells) and tenocytes (tendon cells) to produce collagen type II and proteoglycans — the structural molecules of healthy joints.

Anti-Inflammatory Cytokine Action

Growth biologics modulate the inflammatory microenvironment by upregulating anti-inflammatory cytokines (IL-10, IL-4) while suppressing destructive pro-inflammatory mediators (TNF-α, IL-1β, IL-6) that degrade cartilage.

The Therapy

What Are Growth
Factor Biologics?

"Growth factor biologics" describes biological preparations — such as amniotic tissue and birth tissue products — that are naturally rich in the proteins and cytokines the body uses to coordinate tissue repair.

At JRCU, we use FDA-compliant amniotic and birth tissue preparations sourced from accredited tissue banks. These products contain a natural concentration of growth factors, anti-inflammatory cytokines, and extracellular matrix components. When delivered to a damaged joint via ultrasound-guided injection, they help create a more favorable biological environment for the body's own repair processes to work.

Mechanisms of Action

Key Biological Components
Found in These Preparations

Amniotic and birth tissue biologics naturally contain a range of proteins that support the healing environment of injured tissue. Here is what research shows about some of the key components found in these preparations.

TGF-β

Transforming Growth Factor-Beta

The master regulator of cartilage repair. TGF-β stimulates chondrocytes to produce collagen type II and aggrecan — the core structural proteins that give cartilage its load-bearing properties. Also suppresses inflammatory macrophage activity.

IGF-1

Insulin-Like Growth Factor 1

IGF-1 stimulates chondrocyte proliferation and proteoglycan synthesis while simultaneously inhibiting the degradative enzymes (aggrecanases, MMPs) that break down cartilage in osteoarthritis and degenerative disc disease.

PDGF

Platelet-Derived Growth Factor

PDGF drives cell migration to the injury site and stimulates proliferation of fibroblasts and smooth muscle cells essential for tendon and ligament repair. Critical for the early vascularization phase of healing.

FGF

Fibroblast Growth Factor

FGF family proteins promote angiogenesis (new blood vessel formation) within healing tissue, ensuring that repair zones receive adequate oxygen and nutrients. FGF-2 in particular supports cartilage and intervertebral disc repair.

VEGF

Vascular Endothelial Growth Factor

VEGF orchestrates the formation of new capillary networks into avascular tissues like cartilage. By improving local blood supply, VEGF ensures that the repair process is sustained over the full 3–6 month healing arc.

BMP-7

Bone Morphogenetic Protein 7

BMP-7 is one of the most potent chondrogenic proteins known. It directly induces mesenchymal stem cell differentiation into cartilage-producing chondrocytes and has shown promise in reversing established articular cartilage defects.

What We Treat

Conditions That Respond
to Growth Factor Therapy

Amniotic and birth tissue biologics may be appropriate for a range of musculoskeletal conditions. Your provider will evaluate whether this option is right for your specific case.

Knee Osteoarthritis

Growth factors slow cartilage breakdown, reduce synovial inflammation, and stimulate new matrix production in the joint space.

Hip Joint Degeneration

Targeted delivery of TGF-β and IGF-1 into the hip joint addresses degenerative changes and restores range of motion.

Tendinopathy

Rotator cuff, Achilles, patellar, and elbow tendinopathies respond well to PDGF and FGF-driven collagen remodeling.

Degenerative Disc Disease

Growth factors delivered to the disc's nucleus pulposus or annulus fibrosus support disc cell survival and extracellular matrix restoration.

Ligament & Meniscus Injuries

PDGF and VEGF accelerate the healing of partial ligament tears and meniscus lesions that conventional care struggles to resolve.

Cartilage Defects

Focal cartilage lesions — from sports injury or progressive wear — can be addressed with BMP-7 and TGF-β to promote chondrogenesis.

Healing Timeline

The Repair Cascade
After Growth Factor Therapy

Healing is a biological process. Understanding the timeline helps set the right expectations.

Day 1–3

Growth factors bind to target cell receptors; acute inflammation is modulated; pain may temporarily increase before decreasing.

Week 2–4

Anti-inflammatory cytokine activity peaks; local stem cells are recruited; early collagen synthesis begins in the repair zone.

Month 2–3

Structural tissue remodeling accelerates; new extracellular matrix is laid down; most patients notice significant functional improvement.

Month 4–6+

Collagen matures and cross-links; cartilage density increases on follow-up imaging; peak pain relief and restored biomechanics.

Our Process

Growth Biologics at JRCU:
Your Treatment Journey

Every protocol is customized to your biology, your condition, and your goals.

1

Comprehensive Evaluation

We review your imaging, lab work, and symptom history to determine whether growth factor biologics are indicated and which specific preparation will yield the best outcome for your condition.

2

Protocol Design

Our provider selects the optimal growth factor preparation — concentration, volume, and combination — based on the specific tissue being targeted and the degree of degeneration or injury present.

3

Ultrasound-Guided Delivery

Biologics are injected under real-time ultrasound imaging guidance, ensuring delivery to the precise anatomical target — joint space, tendon insertion, disc, or ligament.

4

Monitored Recovery

We schedule follow-up appointments at defined intervals to assess your response and determine whether additional treatments are needed to maximize your outcomes.
