Advances in ex vivo expansion of hematopoietic stem and progenitor cells for clinical applications.

As caretakers of the hematopoietic system, hematopoietic stem cells assure a lifelong supply of differentiated populations that are responsible for critical bodily functions, including oxygen transport, immunological protection and coagulation. Due to the far-reaching influence of the hematopoietic system, hematological disorders typically have a significant impact on the lives of individuals, even becoming fatal. Hematopoietic cell transplantation was the first effective therapeutic avenue to treat such hematological diseases.

Evaluation of the theranostic potential of [Cu]CuCl in glioblastoma spheroids.

Background: Glioblastoma is an extremely aggressive malignant tumor with a very poor prognosis. Due to the increased proliferation rate of glioblastoma, there is the development of hypoxic regions, characterized by an increased concentration of copper (Cu). Considering this, Cu has attracted attention as a possible theranostic radionuclide for glioblastoma.

Hypothermic Preservation of Adipose-Derived Mesenchymal Stromal Cells as a Viable Solution for the Storage and Distribution of Cell Therapy Products.

Cell and gene therapies (CGT) have reached new therapeutic targets but have noticeably high prices. Solutions to reduce production costs might be found in CGT storage and transportation since they typically involve cryopreservation, which is a heavily burdened process. Encapsulation at hypothermic temperatures (e.

Influence of the mesenchymal stromal cell source on the hematopoietic supportive capacity of umbilical cord blood-derived CD34-enriched cells.

Background: Umbilical cord blood (UCB) is a clinically relevant alternative source of hematopoietic stem/progenitor cells (HSPC). To overcome the low cell number per UCB unit, ex vivo expansion of UCB HSPC in co-culture with mesenchymal stromal cells (MSC) has been established. Bone marrow (BM)-derived MSC have been the standard choice, but the use of MSC from alternative sources, less invasive and discardable, could ease clinical translation of an expanded CD34 cell product.

Tailored Cytokine Optimization for Culture Platforms Targeting the Expansion of Human Hematopoietic Stem/Progenitor Cells.

Umbilical cord blood (UCB) has been established as an alternative source for hematopoietic stem/progenitor cells (HSPC) for cell and gene therapies. Limited cell yields of UCB units have been tackled with the development of cytokine-based expansion platforms. To improve the effectiveness of these platforms, namely targeting clinical approval, in this study, we optimized the cytokine cocktails in two clinically relevant expansion platforms for HSPC, a liquid suspension culture system (CS_HSPC) and a co-culture system with bone marrow derived mesenchymal stromal cells (BM MSC) (CS_HSPC/MSC).

Multicenter, Randomized Clinical Trial to Assess the Effectiveness of Intravitreal Injections of Bevacizumab, Triamcinolone, or Their Combination in the Treatment of Diabetic Macular Edema.

Background And Objective: To evaluate the efficacy of combined bevacizumab-triamcinolone intravitreal injection in the treatment of diabetic macular edema (DME) compared to monotherapy.

Patients And Methods: At eight clinical sites, 111 patients with DME were randomly assigned to receive an intravitreal injection of bevacizumab (Avastin; Genentech, South San Francisco, CA), triamcinolone (Ophthalmos Pharmaceutical Industry, São Paulo-SP, Brazil), or their combination. The primary outcome was visual acuity (VA) at 6 months' follow-up.

[Ophthalmic manifestations of neuroendocrine carcinoma: case report].

Ophthalmic manifestations of neuroendocrine carcinoma. This case report describes the clinical presentation, diagnosis and treatment of a case of neuroendocrine carcinoma. A 43-year-old man presented with ocular manifestation due to orbital and brain metastasis of neuroendocrine carcinoma.

Clinicopathologic study after submacular removal of choroidal neovascular membranes treated with verteporfin ocular photodynamic therapy.

Purpose: To report the clinicopathologic findings after submacular removal of choroidal neovascular membranes (CNV) treated with verteporfin ocular photodynamic therapy.

Design: Interventional case series.

Methods: Retrospective review of eight eyes of eight patients who underwent submacular surgery for CNV after having previously received verteporfin ocular photodynamic therapy for presumed ocular histoplasmosis (one patient), age-related macular degeneration ([AMD] three patients) pathologic myopia (two patients), punctate inner choroiditis (one patient), and idiopathic CNV (one patient).

Effects of the pulsed electron avalanche knife on retinal tissue.

Objectives: To evaluate the precision of retinal tissue dissection by the pulsed electron avalanche knife (PEAK) and to assess possible toxic effects from this device.

Methods: To demonstrate precision of cutting, bovine retina (in vitro) and rabbit retina (in vivo) were incised with the PEAK. Samples were examined by scanning electron microscopy and histologic examination (light microscopy).
