Modelling hematopoiesis mediated by growth factors with applications to periodic hematological diseases [PDF]
Bulletin of Mathematical Biology 68, 8 (2006) 2321-2351, 2009 Hematopoiesis is a complex biological process that leads to the production and regulation of blood cells. It is based upon differentiation of stem cells under the action of growth factors. A mathematical approach of this process is proposed to carry out explanation on some blood diseases, characterized by oscillations in circulating blood cells.

Stability Analysis of a Simplified Yet Complete Model for Chronic Myelegenous Leukemia [PDF]
Bulletin of Mathematical Biology 72, 7 (2010) 1732-1759, 2009 We analyze the asymptotic behavior of a partial differential equation (PDE) model for hematopoiesis. This PDE model is derived from the original agent-based model formulated by (Roeder et al., Nat. Med., 2006), and it describes the progression of blood cell development from the stem cell to the terminally differentiated state.

Osteopetrosis: a rare case of portal hypertension
Future Science OA, 2022 Osteopetrosis is a rare genetic bone disorder characterized by a defect in osteoclasts recruitment and function. Its manifestations are numerous and they mainly include skeletal and dental deformities, cranial nerve entrapment and infections.

Liver metastasis of breast carcinoma: An unusual presentation and growth pattern
Indian Journal of Pathology and Microbiology, 2023 Breast carcinoma is one of the tumors that frequently metastasize to the liver. Extramedullary hematopoiesis (EMH) usually occurs due to insufficient medullary hematopoiesis.

An 80-year-old woman with myelofibrosis and diffuse mosaic attenuation on chest computed tomography
Respiratory Medicine Case Reports, 2022 An 80-year-old woman with myelofibrosis sought evaluation for progressive dyspnea. Her past medical history included essential thrombocytosis, which transformed to myelofibrosis.

Blood Cancer Journal, 2018 Background : Extramedullary hematopoiesis (EMH) implies the production of erythroid and myeloid progenitor cells outside of the bone marrow. EMH in adults is typically seen in patients with myeloproliferative neoplasms (MPN).

BioMed Research International, 2019 Background Extramedullary hematopoiesis (EMH) is common in non-transfusion-dependent thalassemia (NTDT) patients. Clinical presentations of EMH vary as MRI screening is not feasible. Hence, serum biomarkers are used to predict the risk of EMH.

Multifocal extramedullary hematopoiesis in a 15-year-old girl with beta thalassemia: A case report
Radiology Case Reports, 2022 Extramedullary hematopoiesis is a rare disorder in which hematopoietic cells proliferate in tissues other than the bone marrow as a result of a range of hematologic illnesses.

Bayesian inference and model choice in a hidden stochastic two-compartment model of hematopoietic stem cell fate decisions [PDF]
Annals of Applied Statistics 2009, Vol. 3, No. 4, 1695-1709, 2010 Despite rapid advances in experimental cell biology, the in vivo behavior of hematopoietic stem cells (HSC) cannot be directly observed and measured. Previously we modeled feline hematopoiesis using a two-compartment hidden Markov process that had birth and emigration events in the first compartment.

Scientific Reports, 2018 Extramedullary hematopoiesis (EMH) in postnatal life is a pathological process in which the differentiation of hematopoietic stem/progenitor cells (HSPCs) occurs outside the bone marrow (BM) to respond to hematopoietic emergencies.
