A band cell (also called band neutrophil or stab cell) is a cell undergoing granulopoiesis, derived from a metamyelocyte, and leading to a mature granulocyte.
It is characterized by having a nucleus which is curved, but not lobar.[1]
The term "band cell" implies a granulocytic lineage (e.g. neutrophils).[2]

Clinical Significance
Band neutrophils are an intermediary step prior to the complete maturation of segmented neutrophils. An increase in band neutrophils typically means that the bone marrow has been signaled to release more WBCs and increase production of WBCs, also known as a "left shift". Most often this is due to infection or inflammation in the body.
Blood reference ranges for neutrophilic band cells in adults are 3 to 5% of white blood cells,[3] or up to 0.7 x109/L.[4]
An excess is called bandemia.

- Inhibitors of CXC chemokine receptor type 4: putative therapeutic approaches in inflammatory diseases.
- Hummel S, Van Aken H, Zarbock A.Author information aDepartment of Anesthesiology, Intensive Care and Pain Medicine, University of Muenster bMax-Plank Institute Muenster, Muenster, Germany.AbstractPURPOSE OF REVIEW: The CXC chemokine receptor type 4 (CXCR4), which is a G-protein coupled receptor, and its ligand CXCL12 play an important role in neutrophil homeostasis and inflammation. This review focuses on involvement of the CXCL12/CXCR4 axis in inflammation and different inflammatory diseases and depicts that blocking CXCR4 is an attractive therapeutic strategy.

- Lipopolysaccharide-Binding Protein as Marker of Fetal Inflammatory Response Syndrome after Preterm Premature Rupture of Membranes.
- Pavcnik-Arnol M, Lucovnik M, Kornhauser-Cerar L, Premru-Srsen T, Hojker S, Derganc M.Author information Department of Paediatric Surgery and Intensive Care, University Medical Centre Ljubljana, Ljubljana, Slovenia.AbstractBackground: Intra-amniotic inflammation with preterm premature rupture of membranes (PPROM) is a risk factor for fetal inflammatory response syndrome (FIRS) and adverse neonatal outcome. Objectives: To evaluate the diagnostic accuracy of lipopolysaccharide-binding protein (LBP) for detecting FIRS in preterm neonates born after PPROM. Methods: This was a prospective study in the level III neonatal intensive care unit (42 neonates; 23 + 6 to 31 + 6 weeks' gestation) of mothers with PPROM. Umbilical cord blood concentrations of LBP, C-reactive protein (CRP), interleukin (IL)-6 and white blood cell count with differential were measured at delivery and 24 h after birth. Neonates were classified into FIRS (n = 22) and no FIRS (n = 20) groups according to clinical criteria and IL-6 level (≥17.5 pg/ml). Histological examination of the placenta and umbilical cord was performed. Neurological examination at 12 months' corrected age was performed. Results: Umbilical cord blood concentration of LBP was significantly higher in the FIRS group than in the no FIRS group at delivery (median 21.6 mg/l vs. median 2.3 mg/l; p < 0.0001) and 24 h after birth (median 17.2 mg/l vs. median 20.0 mg/l; p < 0.001). The area under the ROC curve for FIRS at delivery was 0.98 (95% CI 0.88-1.0) for LBP, 0.92 (95% CI 0.80-0.99) for CRP and 0.82 (95% CI 0.64-0.94) for immature to total neutrophil ratio. Similar results were obtained if FIRS was defined by funisitis. Umbilical cord blood concentration of LBP at delivery was significantly higher in neonates with abnormal neurological exam at 12 months than in those with normal exam (median 19.5 mg/l vs. median 3.75 mg/l; p < 0.015). Conclusions: In preterm neonates born to asymptomatic women with PPROM, LBP in cord blood at delivery is an excellent diagnostic biomarker of FIRS/funisitis with prognostic potential. © 2013 S.
