This study concluded that blood donors on certain medications can donate blood products with less than 50 ml single-donor plasma for adult use without deferral, except for those taking specific medications like retinoids and genotoxic drugs.

This study found that combining bone marrow aspirate concentrate with platelet-rich plasma significantly improved wound healing in mice compared to other treatments.

This study found that using a centrifugation speed of 1800 rpm for 10 minutes is optimal for preparing platelet-rich plasma with PRPBAG®, yielding an eightfold increase in platelet concentration.

This study found that bioactive glass-based camouflage composite particles enhanced the coagulation effects in bleeding models by forming a fibrin network and activating coagulation pathways, suggesting potential use as an emergency hemostasis biomaterial.

This study found that a simple two-step method for preparing platelet-rich plasma produced satisfactory quality at a lower cost compared to many commercial systems, enabling smaller medical institutions to utilize PRP therapy.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

The study found that the quality of cord blood units remains consistent before freezing and after thawing, indicating that attached tube segments reliably represent the graft's properties.

This study found that FDA-cleared devices for preparing platelet-rich plasma showed inconsistent product quality, with variable platelet counts and inadequate quality control performance, suggesting clinical improvement may not rely on platelet concentration.

In this study, sequential strip harvest during follicular unit transplantation yielded more grafts, significantly improving the recipient area's appearance and minimizing donor area scars, compared to traditional methods.

A new method improves the isolation of hair follicle cells for better hair growth research.

This study reports that using stamps to mark scalp incisions with gentian violet ink and a barrier film improved incision symmetry and maintained slot visibility for hair graft insertion in the frontal region.

In this study, researchers compared three treatments for stable vitiligo and found that a combination of follicular cell suspension and mini punch grafting resulted in significantly better re-pigmentation after six months compared to using either method alone.

This study describes a new two-step method for effectively removing hair particles from split-thickness skin grafts from the scalp, potentially preventing foreign-body reactions at recipient sites.

This study found that a large number of pelage hair follicle mesenchymal stem cells can be efficiently isolated using two-step Ficoll Density Gradient Sedimentation, promoting hair growth by secreting exosomes in mice.

In this study conducted on rabbits, conventional blood treated with 120% sodium citrate was observed to achieve the highest platelet recovery and enrichment coefficient, while altering sodium citrate concentrate affected levels of growth factors PDGF and TGF-β1 after plasma activation.

In this controlled study on hair transplantation, using autologous plasma as a graft holding solution resulted in better hair follicle cell survival, hair count, and density compared to Ringer's lactate, suggesting plasma's potential to enhance hair graft outcomes.

The punch graft technique effectively redistributes hair to cover bald areas.

This study observed that densely packed follicular unit grafts using the lateral slit technique have high growth rates, even at 72 grafts/cm², contradicting previous findings with older methods.

The microstrip technique for hair transplantation is effective and discreet for patients needing fewer than 1500 grafts.

This study found that the washing method can help differentiate chronic telogen effluvium from mild female pattern hair loss, potentially reducing the need for biopsies.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This study found that PRP injections, prepared using a digital centrifuge with a large-sized sodium citrate tube at low centrifugation speed, significantly improved hair thickness and terminal hair percentage in women with pattern hair loss, with similar results across different preparation methods.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.

This study found that platelet dry powder can be mass-produced from pig blood by adding calcium chloride, resulting in a stable material with high growth factor concentrations, which could enhance supply for industrial product development.

This study concluded that combining vertical and transverse sections of scalp biopsy specimens improves diagnostic yield for certain hair disorders without increasing costs.

This review discusses the applications of autologous platelet concentrates in aesthetic medicine, highlighting that platelet-rich fibrin is favored over platelet-rich plasma due to cost-effectiveness and efficacy, but reports no new clinical results.

This paper reports three cases of hair transplantation using Feily's method, which showed unusual long-lasting dark areas on the scalp, suggesting more than 24 hours of caution might be needed to prevent necrosis.

This article describes a hair transplantation technique that provides excellent results, reduces procedure time, and minimizes damage to follicular units compared to traditional methods.

This study found that interfollicular injection of autologous CD34+ cell-containing PRP preparation improved hair count and thickness in patients with pattern hair loss, with better results than placental extract treatment.

This review analyzes existing literature on platelet-rich plasma for hair loss, discussing its mechanisms and preparation, but reports no new clinical results and highlights the inconsistency of current evidence.
