Abstract

Background

Canine peripheral blood mononuclear cell (PBMC) apheresis using a Baxter-Fenwal CS-3000 Plus automated blood cell separator has not been reported.

Objective

To determine the feasibility and safety of using a CS-3000 Plus blood cell separator with a small volume separation container holder (SVSCH) and small volume collection chamber (SVCC) to harvest canine PBMCs from dogs weighing <50 kg.

Animals

Eight healthy mongrel dogs and 11 client-owned dogs in clinical remission for lymphoproliferative diseases (LPD).

Methods

In this prospective study, aphereses were performed using a Baxter-Fenwal CS-3000 Plus blood cell separator, with or without recombinant human granulocyte colony-stimulating factor (rhG-CSF) treatment.

Results

Aphereses from 6 healthy dogs given rhG-CSF yielded an average of 1.1 × 107 ± 8.2 × 106CD34+ cells/kg. Aphereses from LPD dogs given rhG-CSF yielded an average of 5.4 × 106 ± 3.25 × 106CD34+ cells/kg (= .17). Higher hematocrit in both groups of dogs receiving rhG-CSF correlated with an increased number of CD34+ cells/kg harvested (healthy, = .04; LPD, = .05). Apheresis was well tolerated by all dogs.

Conclusions and Clinical Importance

Canine PBMC apheresis using the Baxter-Fenwal CS-3000 Plus cell separator with an SVSCH and SVCC is a feasible and safe option for harvesting an adequate number of CD34+ peripheral blood progenitor cells from dogs weighing ≥17 kg for hematopoietic cell transplantation.
