Why platelets play a key role in the field of dermatology

When we think of dermatology, we often think of skin diseases and cosmetics. But did you know that platelets, also called thrombocytes, play an important role in this medical field? You may ask: Why are platelets of interest to dermatologists?

Why are platelets of interest to dermatologists?

Platelets are small cell fragments that circulate in the blood and play an important role in blood clotting. When injured, they are activated and help stop the flow of blood. But their role goes far beyond blood clotting. In dermatology, the medical specialty that deals with the skin and its diseases, platelets are of particular interest for good reason.

Functions of platelets

Primary hemostasis

When we get injured, the platelets form a plug at the wound to stop the bleeding. This is called primary hemostasis.

Secondary hemostasis

In addition to primary hemostasis, platelets support secondary hemostasis. In this process, they ensure the coagulation of the blood and the closure of the wound to prevent renewed bleeding.

Platelet structure

So let's start with the structure of a platelet - it's a seedless, flat, rounded, round blood cell.

When activated, they release so-called pseudopodia to "close" the vessel.

During this process, the substances for which the platelet is intended (method of administering autologous plasma), namely growth factors that stimulate cell division and growth, are released from the platelet.

⠀

Growth factors are polypeptide molecules with different structures and functions.

⠀

Among the most important growth factors is the

  • platelet-derived growth factor(PDGF), which occurs in the alpha granules of platelets.
  • transforming growth factor(TGF-β), which controls cell proliferation and differentiation.
  • vascular endothelial growth factor(VEGF) - stimulates angiogenesis, restores oxygen supply to tissues);
  • Epithelial growth factor(EGF), which stimulates epidermal growth;
  • Fibroblast growth factor(FGF).

There are three types of platelets:

  • Platelet macrophages: They are the most abundant platelets and account for about 90% of all platelets. They are responsible for thrombus formation.
  • Platelet Adherent Cells: These platelets are responsible for the attachment of platelets to the vessel wall.
  • Platelet granulocytes: These platelets contain a number of pro-inflammatory substances that aid in wound healing.

Platelets play an important role in blood clotting and wound healing. A deficiency of platelets can lead to blood clotting disorders and severe bleeding. An excess of platelets can lead to life-threatening thrombosis.

Platelets in dermatological therapy

The ability of platelets to promote wound healing and tissue regeneration has made them a valuable tool in dermatological therapy. They are used in a variety of treatments, from chronic wound management to aesthetic procedures.

Platelet-rich plasma in dermatology

One of the most notable examples of the use of platelets in dermatology is the use of platelet-rich plasma (PRP). PRP is a concentration of platelets that is extracted from the patient's blood and then injected into areas of the skin that need healing or rejuvenation.

Platelets and chronic wounds

Chronic wounds that are difficult to heal can benefit significantly from the use of platelets. Injecting PRP into the wound can stimulate and accelerate the healing processes.

Research and future applications of platelets in dermatology

Research on platelets and their use in dermatology is an active and exciting field. Future discoveries are expected to lead to new applications and therapies.

Continuous research is being conducted to improve platelet therapies and expand their potential applications in dermatology. From the development of new methods to obtain platelets to the exploration of new therapeutic applications, platelets remain an exciting area in dermatology.

Stem cells and platelets

The combination of stem cells and platelets offers a promising area for future research and could open up new treatment options for a range of skin diseases.

Platelets and skin aging

Research in skin aging and platelets could reveal new ways to combat signs of aging and lead to improved aesthetic procedures.

Why are platelets important in dermatology?

Platelets and wound healing

Platelets contribute to wound healing by promoting the growth of new skin cells and reducing inflammation. This is particularly important in dermatology, as many skin diseases and injuries require rapid and effective wound healing.

Platelets and skin diseases

Some skin diseases, such as psoriasis, may be aggravated by increased platelet activity. Therefore, it is important to monitor the platelet count in patients with such diseases.

Platelets and aesthetic treatments

Platelet therapies such as platelet-rich plasma (PRP) therapy are used in aesthetic dermatology. This uses the patient's own blood to promote skin rejuvenation and improve the appearance of wrinkles.

Summary

Platelets are of interest to dermatologists for many reasons, including their role in wound healing, their importance in certain skin diseases, and their use in aesthetic treatments such as PRP therapy. As research continues, platelets are expected to play an even greater role in dermatology in the future.

So platelets are not just little helpers in blood clotting, but also play a crucial role in dermatology. They promote healing and rejuvenation of the skin, making them an important component of therapies such as PRP therapy, and are therefore of great interest to dermatologists. Platelets thus play an important role in the health and beauty of our skin.

FAQs

What are platelets?

Platelets are small cell fragments that circulate in the blood and play a crucial role in blood clotting.

Why are platelets important for skin health?

Platelets play a crucial role in skin health. They support wound healing and promote tissue regeneration.

What is platelet-rich plasma (PRP)?

Platelet-rich plasma is a concentration of platelets that is extracted from the patient's blood and then injected into areas of the skin that need healing or rejuvenation.

How are platelets used in dermatology?

Platelets are used in dermatology in a variety of therapies, including the treatment of chronic wounds and aesthetic procedures.

What are the future applications of platelets in dermatology?

Research on platelets and their use in dermatology is an active field. Future applications may include the combination of stem cells and platelets and the use of platelets to combat signs of skin aging.

How do platelets influence wound healing?
