Bone marrow endothelial dysfunction promotes myeloid cell expansion in cardiovascular disease.

Nat Cardiovasc Res 2022 Jan 23;1(1):28-44. Epub 2021 Dec 23.

Center for Regenerative Medicine and Cancer Center, Massachusetts General Hospital, Boston, MA, USA.

Abnormal hematopoiesis advances cardiovascular disease by generating excess inflammatory leukocytes that attack the arteries and the heart. The bone marrow niche regulates hematopoietic stem cell proliferation and hence the systemic leukocyte pool, but whether cardiovascular disease affects the hematopoietic organ's microvasculature is unknown. Here we show that hypertension, atherosclerosis and myocardial infarction (MI) instigate endothelial dysfunction, leakage, vascular fibrosis and angiogenesis in the bone marrow, altogether leading to overproduction of inflammatory myeloid cells and systemic leukocytosis.

Rare Case of High Grade Neuroendocrine Carcinoma Found on Bone Marrow Biopsy: A Case Report.

J Community Hosp Intern Med Perspect 2022 31;12(1):83-88. Epub 2022 Jan 31.

New York Cancer and Blood Specialists, Patchogue, USA.

Background: Neuroendocrine neoplasms (NENs) comprise a wide-ranging group of abnormal neoplasms with atypical presentations, from primary localized disease to extensive metastasis, reaching the bone and brain. The NENs are divided into two major groups: neuroendocrine tumors (NETs), which are well-differentiated tumors of any grade, and neuroendocrine carcinomas (NECs), which are poorly differentiated, high-grade cancers with a high risk of morbidity and mortality. The challenge of diagnosing NENs early, particularly prior to metastasis, highlights the importance of further studying these diseases. Read More

In vivo tissue optical clearing assisted through-skull targeted photothrombotic ischemic stroke model in mice.

J Biomed Opt 2022 Jun;27(6)

Huazhong University of Science and Technology, Britton Chance Center for Biomedical Photonics, Wuhan, China.

Significance: Photothrombotic stroke is an important and widely used model for ischemic stroke research. However, the significant scattering of the skull during the procedure limits the light's ability to penetrate and focus on its target. Targeted photothrombosis uses surgery-based skull windows to obtain optical access to the brain, but it renders the brain's environment unnatural even before a stroke is established. Read More

Cell-Based HIF1α Gene Therapy Reduces Myocardial Scar and Enhances Angiopoietic Proteome, Transcriptomic and miRNA Expression in Experimental Chronic Left Ventricular Dysfunction.

Front Bioeng Biotechnol 2022 12;10:767985. Epub 2022 May 12.

Division of Cardiology, Department of Internal Medicine II, Medical University of Vienna, Vienna, Austria.

Recent preclinical investigations and clinical trials with stem cells mostly studied bone-marrow-derived mononuclear cells (BM-MNCs), which so far failed to meet clinically significant functional study endpoints. BM-MNCs containing small proportions of stem cells provide little regenerative potential, while mesenchymal stem cells (MSCs) promise effective therapy paracrine impact. Genetic engineering for rationally enhancing paracrine effects of implanted stem cells is an attractive option for further development of therapeutic cardiac repair strategies. Read More

Biology of Bone Morphogenetic Proteins in skeleton disease: Osteonecrosis in Sickle cell disease patients.

Curr Protein Pept Sci 2022 May 30. Epub 2022 May 30.

Department of pathology, Shyam Shah Medical College, Rewa, M.P.

Sickle cell disease (SCD) is an autosomal recessive trait of genetic hemoglobin disorder whose prevalence is varied from 5 to 25 % of the world population. It is characterized by the presence of hemoglobin (HbS) instead of normal hemoglobin (HbA). An individual suffering from sickle cell disease is likely to be at risk of osteonecrosis which is a form of ischemic bone infarction which causes intolerable degenerative joint problems and can affect 30-50% of people with sickle cell disease.

Growth factors: avenues for the treatment of myocardial infarction and potential delivery strategies.

Regen Med 2022 Aug 31;17(8):561-579. Epub 2022 May 31.

Department of Cardiology, First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, 450052, China.

Acute myocardial infarction (AMI) is one of the leading causes of death worldwide. Despite recent advances in clinical management, reoccurence of heart failure after AMI remains high, in part because of the limited capacity of cardiac tissue to repair after AMI-induced cell death. Growth factor-based therapy has emerged as an alternative AMI treatment strategy. Read More
