This paper describes the rationale and key aspects of how one school-university partnership leveraged resources to create, implement and refine an innovative professional pathway called the Early Childhood Certificate (ECC) program which reflects the National Professional Development Schools (NAPDS) Essential Guideline 4: Reflection and Innovation. The ECC program is an innovative, career-building model that leverages resources between a predominantly white regional state university, a nonprofit organization serving as a Head Start grantee, a large urban school district and community-based education settings across a Midwestern metropolitan region.

This descriptive narrative documents how the ECC program developed as a professional pathway for early childhood educators to scale up their skills for teaching young children while strengthening their capacities and credentials within the early childhood education (ECE) profession pipeline. The narrative includes relevant literature and examples from the field.

This paper includes a discussion of the benefits and challenges related to the design, implementation and refinement of the professional learning ECC program.

This is a descriptive narrative. As such, generalizability is lacking. Research is needed to determine the effectiveness and sustainability of innovative teacher education programs.

Relevant research and lessons learned provide guidance for other school–university partnerships to consider how to meet workforce and career needs for educators in the field of ECE.

School–university partnerships can be change agents and positively impact early childhood educators' career development.

This paper addresses the need for understanding how predominantly white early childhood teacher education programs can partner with schools and agencies and then together leverage resources to support workforce and career development opportunities.

Monocytes are a leukocytes’ subset that plays an important role in immunity. Protein kinase B (AKT) is involved in monocytes' survival, proliferation and differentiation. Using phorbol 12-myristate 13-acetate (PMA) as an inducer for cell line U937 differentiation into macrophage-like cells may be used as a model for cancer cell therapy or other biomedical research studies. The authors investigated the Akt1 signaling pathway's involvement with PMA as a differentiating agent and survival in the U937 cell line.

PMA was utilized to stimulate the differentiation of the U937 cell line into macrophage-like cells at a concentration of 10 nM. Akt1-phosphorylated Serine 473, Bad-phosphorylated Serine 136 and Caspase9-phosphorylated Serine 196 were tested by flow cytometry for the involvement of the Akt1 signaling pathway during differentiation in addition to the expression of CD14, CD206 and CD83. DNA cell cycle variation analysis was done using PI staining and cell viability and apoptosis detection using Annexin V and PI flow cytometry.

There was a decrease in phosphorylated Akt1 and Bad activation and an increase in Caspase9 activation, with an increase in surface markers CD14, CD206 and CD83 acquired by PMA-differentiated cells. DNA cell cycle analysis revealed cell accumulation in the G2/M phase and fewer cells in the S phase of PMA-induced U937. Apoptosis induction for Ly294002 or Wortmannin-inhibited cells and part of PMA-induced cells were detected.

These results may be used to create a model for biomedical research studies and advance the understanding of the mechanism involving differentiation of the U937 cell line.
