Depreciation and amortization expense was $1.3 million and $0.4 million for the three months ended March 31, 2023 and 2022, respectively. The increase in expense is primarily due to the completion of the Company's good manufacturing practice (GMP) cell processing and vector manufacturing suite at the Company's office in Redwood City, California (1000 Bridge Parkway) in February 2023. Construction in progress has decreased by $7.5 million during the three months ended March 31, 2023, compared to the balance at December 31, 2022 due to the Company's completion of the Company's GMP cell processing and vector manufacturing suite in February 2023. The remaining $1.8 million in construction in progress as of March 31, 2023 is primarily related to lab and computer equipment not yet placed into service.
