Question 1

PROMOTION OF CELL PROLIFERATION AND MIGRATION

Accepted Answer

Enhanced Keratinocyte Activity:
MSC exosomes can promote the proliferation and migration of keratinocytes, the primary cells in the epidermis, which are crucial for re-epithelialization and wound closure.

Fibroblast Proliferation:
They stimulate fibroblast proliferation and migration, which are essential for the formation of new connective tissue and extracellular matrix (ECM) deposition.

Modulation of Immune Responses:
They can modulate immune cell activity in the eye, reducing the release of pro-inflammatory cytokines and promoting an anti-inflammatory environment.

Question 2

REDUCTION OF INFLAMMATION

Accepted Answer

Anti-inflammatory Properties:
MSC exosomes have strong anti-inflammatory effects, reducing the infiltration of inflammatory cells and the release of pro-inflammatory cytokines at the wound site, which helps to create a conducive environment for healing.

Modulation of Immune Response:
They modulate the immune response, promoting a shift from a pro-inflammatory to a healing phenotype.

Question 3

ENHANCEMENT ANGIOGENESIS

Accepted Answer

Promotion of Blood Vessel Formation:
MSC exosomes can enhance angiogenesis, the formation of new blood vessels, which is critical for supplying nutrients and oxygen to the wound site, thus accelerating healing.

Improvement of Vascular Endothelial Cell Function:
They support the function of vascular endothelial cells, contributing to better blood supply and faster wound healing.

Question 4

STIMULATION OF COLLAGEN PRODUCTION AND ECM REMODELING

Accepted Answer

Collagen Synthesis:
MSC exosomes can stimulate the production of collagen by fibroblasts, which is vital for wound strength and integrity.

ECM Remodeling:
They aid in the remodeling of the extracellular matrix, which is essential for the restoration of normal tissue architecture.

Question 5

REDUCTION OF SCAR FORMATION

Accepted Answer

Anti-fibrotic Effects:
MSC exosomes can reduce fibrosis and scar formation by modulating the activity of myofibroblasts, the cells responsible for excessive collagen deposition.

Balanced Healing:
They promote a balanced healing response that minimizes scar tissue formation and maximizes functional tissue regeneration.

Question 6

ANTIOXIDANT EFFECTS

Accepted Answer

Reduction of Oxidative Stress:
Exosomes contain antioxidant properties that help reduce oxidative stress at the wound site, protecting cells from damage and promoting healing.

Question 7

ENHANCED RE-EPITHELIZATION

Accepted Answer

Accelerated Skin Barrier Restoration:
MSC exosomes can accelerate the re-epithelialization process, restoring the skin barrier function more quickly and effectively.

Question 8

PAIN REDUCTION AND IMPROVED COMFORT

Accepted Answer

Analgesic Effects:
Exosomes may have analgesic effects that help reduce pain associated with wounds, improving patient comfort during the healing process.

Question 9

INFECTION CONTROL

Accepted Answer

Antimicrobial Properties:
MSC exosomes can exhibit antimicrobial properties, helping to reduce the risk of infection at the wound site.

Question 10

GENE AND DRUG DELIVERY

Accepted Answer

Therapeutic Delivery:
Exosomes can be engineered to deliver specific therapeutic molecules, such as growth factors, RNAs, or drugs, directly to the wound site, enhancing their therapeutic efficacy.

Question 11

ANTI-INFLAMMATORY EFFECTS

Accepted Answer

Reduction of Ocular Inflammation:
MSC exosomes have potent anti-inflammatory properties that can help reduce inflammation in ocular tissues, beneficial for conditions such as uveitis, diabetic retinopathy, and age-related macular degeneration (AMD).

Modulation of Immune Responses:
They can modulate immune cell activity in the eye, reducing the release of pro-inflammatory cytokines and promoting an anti-inflammatory environment.

Question 12

PROTECTION AND REGENERATION OF RETINAL CELLS

Accepted Answer

Neuro | Protection:
Exosomes can protect retinal ganglion cells and photoreceptors from damage due to oxidative stress, inflammation, or hypoxia, which is crucial for conditions like glaucoma and AMD.

Promotion of Retinal Cell Survival:
They promote the survival and function of retinal cells, aiding in the recovery from retinal injuries or degenerative diseases.

Question 13

ENHANCEMENT OF CORNEAL HEALING

Accepted Answer

Corneal Epithelial Repair:
MSC exosomes can accelerate the repair and regeneration of corneal epithelial cells, improving healing in cases of corneal injuries, ulcers, or surgeries.

Reduction of Corneal Scarring:
They can reduce fibrosis and scarring in the cornea, leading to better visual outcomes.

Question 14

TREATMENT OF OCULAR SURFACE DISORDERS

Accepted Answer

Dry Eye Syndrome:
Exosomes can improve tear production and reduce inflammation, providing relief for dry eye syndrome.

Improvement of Wound Healing:
They enhance the healing of the ocular surface following injuries or surgeries, promoting faster recovery and better outcomes.

Question 15

ANTI-APOPTOTIC EFFECTS

Accepted Answer

Protection Against Cell Death:
MSC exosomes can inhibit apoptosis (programmed cell death) in ocular cells, protecting against cell loss in conditions such as retinal detachment and optic neuropathies.

Question 16

PROMOTION OF ANGIOGENESIS

Accepted Answer

Vascular Repair:
Exosomes can promote the formation and repair of blood vessels in the retina, which is beneficial for ischemic retinal diseases and diabetic retinopathy.

Regulation of Neovascularization:
They can modulate abnormal blood vessel growth, which is crucial in conditions like neovascular AMD.

Question 17

REDUCTION OF OXIDATIVE STRESS

Accepted Answer

Antioxidant Effects:
Exosomes contain antioxidants that can reduce oxidative stress in ocular tissues, helping to prevent or slow the progression of degenerative eye diseases.

Question 18

DELIVERY OF THERAPEUTIC MOLECULES

Accepted Answer

Drug and Gene Delivery:
Exosomes can be engineered to deliver specific therapeutic molecules, such as drugs, RNAs, or proteins, directly to ocular cells, enhancing their therapeutic efficacy and targeting specific eye conditions.
